NAME

     remquo -- floating-point remainder and quotient function

SYNOPSIS

     #include <math.h>

     double
     remquo(double x, double y, int *quo);

     long double
     remquol(long double x, long double y, int *quo);

     float
     remquof(float x, float y, int *quo);

DESCRIPTION

     The remquo() 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.  This is the same value that
     is returned by the remainder() function.  remquo() also calculates the lower seven bits of the integral quotient x/y, and gives that value
     the same sign as x/y. It stores this signed value in the object pointed to by quo.

SPECIAL VALUES

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

VECTOR OPERATIONS

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

     #include <Accelerate/Accelerate.h>

     vFloat vremquo(vFloat x, vFloat y, vUInt32 *q);

     math(3), remainder(3)

STANDARDS

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