WebPerl also supports a modulusoperator. The value of the expression 10%3is the remainder when 10 is divided by 3, which is 1. Both values are first reduced to their integer values, so 10.5%3.2is computed as 10%3. The logical comparison operators are < <= == >= > !=, these compare two values numerically, returning a true or falsevalue.
