remainderf

Applicability

Function Usage

Obtains the remainder of input x divided by y. The quotient is rounded to the nearest integer. If the floating-point result of x divided by y is exactly halfway between two integers, the quotient is rounded to the even integer.

Prototype

1

inline float remainderf(float x, float y)

Parameters

Returns

The remainder of input x divided by y.

• If y is 0, the return value is nan.
• If x is inf or -inf, the return value is nan.
• If x is a finite number and y is inf or -inf, the return value is x.
• If either x or y is nan, the return value is nan.
