NAME fmod, fmodf - floating-point remainder functions CONTENTS Library Synopsis Description Return Values See Also Standards LIBRARY .Lb libm 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. SEE ALSO math(3) STANDARDS
