fmodf

Applicability

Function Usage

Obtains the remainder of input x divided by y. The quotient is the integer part of the floating-point result of x divided by y.

Prototype

1

inline float fmodf(float x, float y)

Parameters

Returns

The remainder of input x divided by y.

• If x is 0 and y is not 0, the return value is 0.
• If x is a finite number and y is inf or -inf, the return value is x.
• If x is inf or -inf, or y is 0, the return value is nan.
• If either x or y is nan, the return value is nan.
