What is the modulus operator?

July 24th, 2009 by uCertify Leave a reply »

The modulus operator is a binary arithmetic operator that returns the remainder of the division operation. It can be used with both floating-point values and integer values. The use of the modulus operator is shown as follows:

opL % opR

where, opL is the left operand and opR is the right operand. This expression is equivalent to the expression opL – ((int) (opL / opR) * opR)

Note: The result obtained by the modulus operator is negative if the left operand is negative. Otherwise, the result is positive. The sign of the right operand has no effect on the sign of the result.
