"Mod" - Arithmetic Modulus Operation

This section provides some detail rules and a tutorial example on how arithmetic modulus operation works in VBScript.

Here are some detail rules about the arithmetic operation - modulus:

Here is a tutorial example showing you how arithmetic modulus operation rules work:

   document.writeln("False Mod True=" & (False Mod True) & " : " _
      & TypeName(False Mod True))
   document.writeln("Empty Mod 3=" & (Empty Mod 3) & " : " _ 
      & TypeName(Empty Mod 3))

Here is the output of this VBScript example script:

21 Mod 7=0 : Integer
20.6 Mod 7=0 : Long
24 Mod 7=3 : Integer
24 Mod 6.6=3 : Long
24 Mod 6.4=0 : Long
3 Mod 777777=3 : Long
3 Mod 9.99=3 : Long
3.33 Mod 9.99=3 : Long
3 Mod "7"=3 : Long
3 Mod True=0 : Integer
False Mod True=0 : Integer
Empty Mod 3=0 : Integer

The output confirms some of arithmetic modulus operation rules:
