floating-point remainder function
#include
<math.h>
double
remainder
(double
x, double y);
long double
remainderl
(long
double x, long double
y);
float
remainderf
(float
x, float y);
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.
remainder
(x,
y) returns a NaN and raises the "invalid" floating-point
exception if x is infinite or y is 0.
The
drem
()
function is deprecated. Please use the C99 function
remainder
() instead.
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);
The remainder
() functions conform to
ISO/IEC 9899:2011.
