Get the Decimal Part of a Number in Excel

How to get the decimal part of a number without any rounding in Excel.

This tip allows you to simply remove the whole number, integer, from the number in order to return the decimal portion of the number.

To do this, we need to use the TRUNC function inside a small formula.

If the number is in cell A1, use this formula to get the decimal part of the number:

=A1-TRUNC(A1)

This returns:

As you can see, no rounding occurred; it simply output everything after the decimal.

This formula uses the TRUNC function to get the integer from cell A1 and then subtracts that integer from the number in cell A1, which leaves you with the decimal.

If you Evaluate the formula, you will see that the calculation looks like this: 123.8459-123

Notes

This is a simple formula that builds on the TRUNC function in Excel. Similarly, you can get the whole number, integer, part of a number.
