Syntax

MODZ (argument-1, argument-2)


Arguments

argument-1

is a numeric constant, variable, or expression that specifies the dividend.

argument-2

is a non-zero numeric constant, variable, or expression that specifies the divisor.


Details

The MODZ function returns the remainder from the division of argument-1 by argument-2. When the result is non-zero, the result has the same sign as the first argument. The sign of the second argument is ignored.

The computation that is performed by the MODZ function is exact if both of the following conditions are true:

If either of the above conditions is not true, a small amount of numerical error can occur in the floating-point computation. For example, when you use exact arithmetic and the result is zero, MODZ might return a very small positive value or a value slightly less than the second argument.


Comparisons

Here are some comparisons between the MODZ and MOD functions:


Examples

The following SAS statements produce results for MOD and MODZ.
