VBA equivalent to Excel's mod function

excel, excel-2007, vba

Solution

You want the mod operator.

The expression a Mod b is equivalent to the following formula:

a - (b * (a \ b))

Edited to add:

There are some special cases you may have to consider, because Excel is using floating point math (and returns a `float`), which the VBA function returns an integer. Because of this, using `mod` with floating-point numbers may require extra attention:

Excel's results may not correspond exactly with what you would predict; this is covered briefly here (see topmost answer) and at great length here.

As @André points out in the comments, negative numbers may round in the opposite direction from what you expect. The `Fix()` function he suggests is explained here (MSDN).
