What this tool is for
Modulo Calculator supports math checking in math calculators by showing how apply the formula shown on this page to the entered values. The page keeps the inputs, formula, and example together so the calculation can be checked before the number is reused.
When to use it
Use it when dividend and divisor are already known and you need a quick estimate before comparing options, checking a worksheet, or copying the result into another workflow.
Inputs
- Dividend is one of the direct inputs used to calculate modulo.
- Divisor is one of the direct inputs used to calculate modulo.
Formula
modulo = dividend - divisor x floor(dividend / divisor)
Example
17 mod 5 = 2.
What the result means
