REMAINDER(3)						   BSD Library Functions Manual 					      REMAINDER(3)

NAME

     remainder -- floating-point remainder function

SYNOPSIS

     #include <math.h>

     double
     remainder(double x, double y);

     float
     remainderf(float x, float y);

DESCRIPTION

     The remainder() and remainderf() functions compute the value r such that r = x - n*y, where n is the integer nearest the exact value of x/y.

     If there are two integers closest to x/y, n shall be the even one. If r is zero, it is given the same sign as x.

SPECIAL VALUES

     remainder(x, y) returns a NaN and raises the "invalid" floating-point exception if x is infinite or y is 0.

SEE ALSO

     math(3)

STANDARDS

     The remainder() and remainderf() functions conform to ISO/IEC 9899:1999(E).

NAME

     remainder -- floating-point remainder function

SYNOPSIS

     #include <math.h>

     double
     remainder(double x, double y);

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

     float
     remainderf(float x, float y);

DESCRIPTION

     The remainder() functions compute the value r such that r = x - n*y, where n is the integer nearest the exact value of x/y.

     If there are two integers closest to x/y, n shall be the even one. If r is zero, it is given the same sign as x.

SPECIAL VALUES

     remainder(x, y) returns a NaN and raises the "invalid" floating-point exception if x is infinite or y is 0.

NOTE

     The drem() function is deprecated.  Please use the C99 function remainder() instead.

VECTOR OPERATIONS

     If you need to apply the remainder() 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 vremainderf(vFloat x, vFloat y);
     void vvremainderf(float *z, const float *y, const float *x, const int *n);
     void vvremainder(double *z, const double *y, const double *x, const int *n);

SEE ALSO

STANDARDS

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