Mod Operator

This page is specific to the Visual Basic for Applications (VBA) Language Reference for Office 2010.

Used to divide two numbers and return only the remainder.


result = number1 Mod number2

The Mod operator syntax has these parts:




Required; any numeric variable.


Required; any numeric expression.


Required; any numeric expression.


The modulus, or remainder, operator divides number1 by number2 (rounding floating-point numbers to integers) and returns only the remainder as result. For example, in the following expression, A (result) equals 5.

Usually, the data type of result is a Byte, Byte variant, Integer, Integer variant, Long, or Variant containing a Long, regardless of whether or not result is a whole number. Any fractional portion is truncated. However, if any expression is Null, result is Null. Any expression that is Empty is treated as 0.


This example uses the Mod operator to divide two numbers and return only the remainder. If either number is a floating-point number, it is first rounded to an integer.

Dim MyResult
MyResult = 10 Mod 5    ' Returns 0.
MyResult = 10 Mod 3    ' Returns 1.
MyResult = 12 Mod 4.3    ' Returns 0.
MyResult = 12.6 Mod 5    ' Returns 3.
