SYNOPSIS


.In math.h double fmod "double x" "double y" float fmodf "float x" "float y"

DESCRIPTION

The fmod and the fmodf functions compute the floating-point remainder of x / y.

RETURN VALUES

The fmod and the fmodf functions return the value
.Sm off x - i * y,
.Sm on for some integer i such that, if y is non-zero, the result has the same sign as x and magnitude less than the magnitude of y. If y is zero, whether a domain error occurs or the fmod and the fmodf function returns zero is implementation-defined.
