FMOD(3) 								 1								   FMOD(3)

fmod - Returns the floating point remainder (modulo) of the division of the arguments

SYNOPSIS

       float fmod (float  $x, float  $y)

DESCRIPTION

	Returns  the  floating point remainder of dividing the dividend ($x) by the divisor ($y). The remainder ($r) is defined as: x = i * y + r,
       for some integer $i. If $y is non-zero, $r has the same sign as $x and a magnitude less than the magnitude of $y.

PARAMETERS

	      o $x
		- The dividend

	      o $y
		- The divisor

RETURN VALUES

	The floating point remainder of $x/$y

EXAMPLES

       Example #1

	      Using fmod(3)

	      <?php
	      $x = 5.7;
	      $y = 1.3;
	      $r = fmod($x, $y);
	      // $r equals 0.5, because 4 * 1.3 + 0.5 = 5.7
	      ?>

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.
