Presumably you'd be entering N, lambda, D_1 and D_2, and want F_N. If so,
calculate F_N as

I'd need to edit this site's source to find the formulas in the php code.
You wouldn't happen to have a more explicit reference, would you?

I wantt to make a calculator with excel. I know some excel basics, but
I need help with the formula in the link below.

I would also like downtilt and azimuth calculators from the link

http://www.wisp-router.com/calculators/fresnel.php

Again I need help with the formulas. I could use these but I need them
offline also. This is where excel comes in.

I know how to ste the name fields and have an area for the value to be
entered, the formula is killing me.

Thanks

All,

If anyone can help with this, they are a legend. It will save me so much time.

My boss wants me to use the Westbay call centre calculator (http://www.erlang.com/calculator/call/) as they believe this is the most accurate when working out how many agents we need. However, plugging figures in to this calculator is tedious and not time effective (you can tell I work in a call centre), especially when using massive amounts of data.

I have downloaded Erlang C for Excel and I have used the example document which comes in the .zip file. To make this explanation easier I have made a few tweaks to make look it look similar the Westbay calculator in format.

Now to my problem. When figures are plugged in to both calculators the number of agents does not match.

Westbay Calculator


Excel Calculator


Any idea why this is and what I can do to make them match?
Ideally I would like the Excel document to return the exact same figures as the Westbay tool.


Many thanks,
Lee.


Hi all,
The yield function in excel does not give the right value if I play around with the redemption value(% of par). I have checked this with other available online bond yield calculators such as
http://www.moneychimp.com/calculator...e=calc_bondytm

If I change the redemption value to 50 and the bond price to $50, ideally the coupon rate and the yield should be equal for any time period. While this happens in the calculator mentioned above, Excel gives me a different number. Is this actually a bug or am I missing the point?

Test this in Excel...

=YIELD("6/30/2009","6/30/2022",0.0958,50,50,2,0)

Also test different redemption and price values and compare them with the calculator above.


How this type of calculators are made? Any idea!

Hi. First post here, looks like a good place for Excel info.

I'm not really familiar with Excel's iteration and how to set it up properly. Here's an example of a problem that requires iteration:

1 / λ1/2 = -2 log [ 2.51 / (Re λ1/2) + (k / dh) / 3.72 ]

Only one value of lambda (λ) will allow the two equations above to be equal, I need to balance the equations and solve for Lambda. The way I do this now is using VBA (code below)... can this be done without VBA using only Excel and iteration? If so a detailed explanation (using the example above) would be much appreciated.


VBA code to solve above:
Code:

Public Function GetFrictionFactor(rgRe As Range, rgK As Range, rgDh As Range) As Double
  Dim Eqn1 As Double, Eqn2 As Double
  Dim Lambda As Double
  Dim Increment As Double, Tolerance As Double
  
  Lambda = 0.0001
  Increment = 0.000001
  Tolerance = 0.00005

  Do
    Eqn1 = -2 * Log(2.51 / (rgRe.Value * (Lambda ^ 0.5)) + (rgK.Value / rgDh.Value) / 3.72) / Log(10)
    Eqn2 = 1 / (Lambda ^ 0.5)
  
    If Eqn2 - Eqn1

OK, I know that you can use scripts to call calculators such as the following.

Code:

Sub OpCalc_Click()
'Standard Module code!

On Error GoTo Err_OpCalc_Click
ActiveSheet.Select

'Open the Calculator!
Call Shell("Calc.exe", 1)

Exit_OpCalc_Click:
Exit Sub

Err_OpCalc_Click:
MsgBox Err.Description
Resume Exit_OpCalc_Click

End Sub


However, I would like to make my own userform calculator so that I can modify the way it looks, size, font etc... and can add in other things if need be.

Does someone have a worbook that they can provide that has the scripts for a userform calculator that I can then modify the look etc.... to suite my desires.

I have searched the net but haven't found anything worth while.

Thanks


I'm trying to set up a report that calculates fees in order to validate fee
calculations on another system. Column one contains a reference to a fee
schedule; i.e. schedule A, schedule B etc. Column 2 contains the account
value. So I need to look up the appropriate schedule, use the appropriate
calculator and return the result into column 3. Part of my problem is that
the fee calculators are not in a single cell, although I could probably
re-write them if I have to. (The fee calculators discount for higher
balances- i.e. 1.00% of the first $500,00, .85% of the next $500,000, .75% of
the next $1,000,000, etc) Any ideas and/or formatting suggestions would be
appreciated!



Hi
I have a mesh of Networking equipment in my office and we have an excel sheet maintaining the interconnectivity of the routers

Near End Far End
Router-6 Router-5
Router-7 Router-5
Router-5 Router-3
Router-3 Router-4
Router-3 Router-1
Router-1 Router-2
Gateway Router-1

Now as you can see the arrangement of "Near End" and "Far End" is totally arbitrary. The actual connectivity is as follows

Gateway
/
/
/
Router-1
/ \
/ \
/ \
Router-3 Router-2
/ \
/ \
/ \
Router-4 Router-5
/ \
/ \
/ \
Router-6 Router-7
I wish to make a macro that can give me the appropriate "Far End" that connects the node to the gateway. For example given Router-3 the correct "Far End" would be Router-1. The End Result of this macro would be something like this:

Near End Far End
Router-6 Router-5
Router-7 Router-5
Router-5 Router-3
Router-3 Router-1
Router-4 Router-3
Router-2 Router-1
Router-1 Gateway

Any help is highly appreciated.


I have an Excel 2003 spreadsheet used to calculate doses of medication. The value of several cells will depend on what optionbuttons the user selects.

I have entered the first two lines of code below w/o a problem to make certain calculations that are displayed in the specified cells. I then tried to make an additional calculation to display in cell 6,9, but it always triggers a "Application-defined or object-defined error". For troubleshooting purposes, I moved that line of code directly under the other two lines of similar code that I know work, and simplified the problem line to just arbitrarily set the value of the cell to a value of 2 (instead of the actual formula); it still triggers the error.

Code:

'CVM Pharmacy Protocol
Worksheets("CRI CALCULATOR").Cells(16, 3).Value = Worksheets("CRI CALCULATOR").Cells(5, 8).Value / ((Worksheets("CRI CALCULATOR").Cells(15, 3).Value * Worksheets("CRI CALCULATOR").Cells(3, 8).Value) / Worksheets("CRI CALCULATOR").Cells(10, 3).Value)
Worksheets("CRI CALCULATOR").Cells(16, 8).Value = ((Worksheets("CRI CALCULATOR").Cells(5, 8).Value / Worksheets("CRI CALCULATOR").Cells(17, 8).Value) * Worksheets("CRI CALCULATOR").Cells(10, 3).Value) / Worksheets("CRI CALCULATOR").Cells(3, 8).Value
Worksheets("CRI CALCULATOR").Cells(6, 9).Value = 2


I really would appreciate insight as to why this simple change in a cell value is triggering an error. I've attached the file. To trigger the error, pull up the worksheet "CRI Calculator" and click on either of the optionbuttons with blue text, or double-click on a name in the list-box. The worksheet is protected but it has no password, so it should unprotect easily. Thanks!


I have recently made a calculator with UserForm (in Excel 2003) and would like to convert it to an Add-in to distribute to my colleagues. I've read several references as well as a link posted in this forum but still cannot get it save properly.

Most instructions say to start with a new empty workbook but I've already put in a lot of time with this calculator and don't want to remake the userform. The references say I need to add a Toolbar.

I understand the need to unload the toolbar when exiting and some of the concepts but I'm having trouble saving as .xla file.

I've put the following into This Workbook

Private Sub Workbook_BeforeClose()
Toolbars("Calculators").Visible = False
End Sub
Private Sub Workbook_Open()
Toolbars("Calculators").Visible = True
End Sub

When I go to compile I get the following error message that I don't understand.

"Compile error:
Procedure declaration does not match description of event or procedure having the same name"
It then highlights the first Private Sub Workbook_BeforeClose() line. (The info after the help button wasn't helpful to me.)

I took this straight from a book and followed the multiple steps.

Thanks,
Philro


I am trying to create my own dutching calculator but I have become stuck.

Here is an online dutching calculator:
http://www.ukhorseracing.co.uk/tools...Calculator.asp

I also have this one (attached file) but it is locked, so I cannot edit it. I can't even understand how it works as the formula refers to empty cells.

Thanks in advance.

Thanks very much Ron - That'll work just fine.

Hi, I'm trying to set up a direct link to the internal excel calculator, using a button in VBA.

I have the shortcut on my own toolbar, but I have many users that use the workbook, and to get them all to set up is almost impossible, so I am trying to make it simple for them.

I've tried doing it through a hyperlink direct to the calc.exe file, but get a lot of messages popping up (that'll scare a few of them).

So thought I would try and find the excel name for it and use VBA, but I cannot find it anywhere.

Can anyone help ?.


Instead of having to pull up the calculator off the start menu then transfer
that data to excel, it would be great if we could have a way to calculate
within the cell we want the data.

Basicaly the only formula I can use is the if formula but everytime I use it it ends up looking like a mess and the fomulas cause me a headache when I convert it to earlier excel programs

=IF('Cookie Calculator'!$B$3=Sheet1!$B$3,Sheet1!$M4,IF('Cookie Calculator'!$B$3=Sheet1!$C$3,Sheet1!$N4,IF('Cookie Calculator'!$B$3=Sheet1!$D$3,Sheet1!$O4,IF('Cookie Calculator'!$B$3=Sheet1!$E$3,Sheet1!$P4,IF('Cookie Calculator'!$B$3=Sheet1!$F$3,Sheet1!$Q4,IF('Cookie Calculator'!$B$3=Sheet1!$G$3,Sheet1!$R4,IF('Cookie Calculator'!$B$3=Sheet1!$H$3,Sheet1!$S4)))))))+3

Ive even broken some of these formulas up for when there are 2 reference,

=IF($B$1=Sheet1!$A$4,Sheet1!X4-$C5,IF($B$1=Sheet1!$A$5,Sheet1!X8-$C5,IF($B$1=Sheet1!$A$6,Sheet1!X12-$C5,IF($B$1=Sheet1!$A$7,Sheet1!X16-$C5,IF($B$1=Sheet1!$A$8,Sheet1!X20-$C5,IF($B$1=Sheet1!$A$9,Sheet1!X24-$C5,IF($B$1=Sheet1!$A$10,Sheet1!X28-$C5,IF($B$1=Sheet1!$A$11,Sheet1!X32-$C5,IF($B$1=Sheet1!$A$12,Sheet1!X36-$C5,IF($B$1=Sheet1!$A$13,Sheet1!X40-$C5,IF($B$1=Sheet1!$A$14,Sheet1!X44-$C5,IF($B$1=Sheet1!$A$15,Sheet1!X48-$C5,IF($B$1=Sheet1!$A$16,Sheet1!X52-$C5,IF($B$1=Sheet1!$A$17,Sheet1!X56-$C5,IF($B$1=Sheet1!$A$18,Sheet1!X60-$C5,IF($B$1=Sheet1!$A$19,Sheet1!X64-$C5))))))))))))))))

As you can see this is starting to become a bit of a mess, could someone tell me where I can go to learn about formulas in english so I know which one to use and when.

I have attached a worksheet so you can see how I make a simple thing turn into a big episode due to not understanding what formula to use where.


Hello,
I am trying to set up a Calculator which results in the Number of Roof Tiles I need for a House construction.
Most of the Calculators I have found are imperial but I need metric.

Does anyone have any ideas please
Thanks

I have attached an example




Hi all,

Been a closet viewer for a while now so finally decided to become a member and try and help out.
I have a vast experience using excel and im a modest VBA programmer.
I generally build shop floor production gantt charts in excel enginerring calculators and wage/overtime calculators etc.
I also build html and php websites but mainly utilise the open source code to create them these days.

Have a good day and ill see you round.

Dan.



Hi everyone!
I need a little help here please, I need a Search Engine that displays the query results in an alphabetical/alphanumerical order. I have provided a Sample Workbook, and a Link to the Original Thread, these are listed below.

So the search engine part is fine, but the issue at hand is getting Excel to display the results alphabetically. I understand the reason that they are not is due to the way Excel is ranking the results as relevent to the query. I am fairly new to using basic formulas to make Excel do what I want, and also new to actually understanding how the formulae work, so any information on this, tips&tricks, or if someone wants to edit the formulae within the Sample Workbook to force the Search Engine to display the query results in an alphabetical/alphanumerical order, would prove extremely useful. Thank you!!!

FYI: The Search Engine pulls from the Column labeled "Site_PCode" in every tab, so if you type "b" within the "PostCode Fragment" Query cell on the "Search" tab, and then note the way the results are displayed, you will understand what I mean.

Original Thread: http://www.excelforum.com/excel-gene...readsheet.html
Sample Workbook: http://www.excelforum.com/attachment...atrix-new.xlsx

I have a spreadsheet where my calculation ( results ) should be the same as if you were to calculate the same input as on a calculator.

Example :

Cell A = .351
Cell B = 9.444
Cell C = 34.444

When I use the following formula : A / B*C = 1.28011 is my answer

When I calculate the same thing on a calculator my result is 1.28055

This gives me a variance of -0.044% which I cannot "use" because this can cause an incremental increase which I cannot allow for my calculations.

Is there any advice or guidance that anyone can give to help me with this? I basically need my numbers to "match" what will calc out on a calculator for those who do not have access to Excel. Thanks in advance.


I have found a on line calculator. What formula I have to use in excel to get the same result?

Current age:30
Monthly pension required from age 60 (Rs.) 5000
Growth rate per anum 10

The answers comes as :
Annual premium payable till age 60 (Rs.) 7,267
Retirement fund available at age 60 (Rs.) 817,381

Hello

I have built a quite extensive loan calculator, for both Annuitet and even repayments, and the calculator is working fine.
The formulas for it are a bit complex (perhaps I wrote them a bit too complicated )

Anyway, I want to be able to pay into the principal amount at any given time in the model, but I have no idea how to adjust the formulas to replicate that?
Can anyone assist?

I have attached the document for further verification.

MAny Thanks!
