#include <math.h>
double remainder( double x,
double y );
float remainderf( float x,
float y );
long double remainderl( long double x,
long double y );

Arguments:

x

The numerator of the division.

y

The denominator.

Library:

libm

The general-purpose math library.

libm-sve

(QNX Neutrino 7.1 or later)
A library that optimizes the code for ARMv8.2 chips that have Scalable Vector Extension hardware.

Your system requirements will determine how you should work with these libraries:

If you want only selected processes to run with the SVE version, you can include both libraries in your OS image
and use the -l m or -l m-sve option to
qcc
to link explicitly against the appropriate one.

If you want all processes to use the SVE version, include libm-sve.so in your OS image
and set up a symbolic link from libm.so to libm-sve.so.
Use the -l m option to
qcc
to link against the library.

Note:
Compile your program with the -fno-builtin option to prevent the compiler from using a
built-in version of the function.

Description:

These functions return the floating point remainder
r = x - ny,
where y is nonzero.
The value n is the integral value nearest the exact value
x/y.
When |n - x/y| = ½,
the value n is chosen to be even.

The behavior of remainder() is independent of the rounding mode.
