NAME

     fmod -- floating-point remainder function

SYNOPSIS

     #include <math.h>

     double
     fmod(double x, double y);

     float
     fmodf(float x, float y);

DESCRIPTION

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

     Specifically, the functions return the value x-i*y, 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.

SPECIAL VALUES

     fmod(+-0, y) returns +-0 for y not zero.

     fmod(x, y) returns a NaN and raises the "invalid" floating-point exception for x infinite or y zero.

     fmod(x, +-infinity) returns x for x not infinite.

SEE ALSO

     math(3)

STANDARDS

     The fmod() and fmodf() functions conform to ISO/IEC 9899:1999(E).

NAME

     fmod -- floating-point remainder function

SYNOPSIS

     #include <math.h>

     double
     fmod(double x, double y);

     long double
     fmodl(long double x, long double y);

     float
     fmodf(float x, float y);

DESCRIPTION

     The fmod() functions compute the floating-point remainder of x/ y.

     Specifically, the functions return the value x-i*y, 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.

SPECIAL VALUES

     fmod(+-0, y) returns +-0 if y is neither 0 nor NaN.

     fmod(x, y) returns a NaN and raises the "invalid" floating-point exception for x infinite or y zero.

     fmod(x, +-infinity) returns x for x not infinite.

VECTOR OPERATIONS

     If you need to apply the fmod() functions to SIMD vectors or arrays, using the following functions provided by the Accelerate.framework may
     give significantly better performance:

     #include <Accelerate/Accelerate.h>

     vFloat vfmodf(vFloat x, vFloat y);
     void vvfmodf(float *z, const float *y, const float *x, const int *n);
     void vvfmod(double *z, const double *y, const double *x, const int *n);

STANDARDS

     The fmod() functions conform to ISO/IEC 9899:2011.
