MacXL: MOD() Function Returns #NUM! Error Value (299504)


The information in this article applies to:

  • Microsoft Excel 2001 for Mac
  • Microsoft Excel 98 Macintosh Edition

SYMPTOMS

The MOD() function in Microsoft Excel may return a #NUM! error value instead of a valid remainder (modulus).

CAUSE

The MOD() function returns the #NUM! error if the following condition is true:

('divisor' * 134217728) is less than or equal to 'number'

WORKAROUND

If the above condition is true, and the MOD() function returns a #NUM! error, you can use the following formula to calculate the remainder (modulus) of two numbers:

=number-(INT(number/divisor)*divisor)

For example, instead of using this formula

=MOD(J13,K13)

use this formula:

=J13-(INT(J13/K13)*K13)

MORE INFORMATION

In Microsoft Excel, the MOD() function returns the remainder (modulus) of dividing one number by another. The MOD() function accepts two arguments: 
   Argument   Definition
   --------------------------------------
   Number     The number being divided
   Divisor    The number being divided by
If you want to calculate the remainder (modulus) of 22 divided by 5, you would use the following formula:

=MOD(22,5)

The result is 2 (22 divided by 5 leaves a remainder of 2).

If the divisor argument, multiplied by 134,217,728 (or 2 raised to the 27th power), is less than or equal to the number argument, the MOD() function returns a #NUM! error value.
