I am using Excell to calculate codes to enter into an e2prom to generate frequencies in a radio being used for ham radio purposes. I divide the required frequency by 0.00625 to get a number which is converted to hexidecimal. When I divide 145.00 by 0.00625 I get 23200 which is correct but when I divide the next frequency of 145.0125 I get 23201 instead of 23202 then the next frequency is 145.025 and dividing by 0.00625 the result is 23204 which is correct. Before I had excell I used the spreadsheet in Microsoft Works and using the easycalc function in that the results always were correct. Can anyone help please.
