    NAME

     - minimal residue functions
    
     
    

    LIBRARY

    SYNOPSIS

       #include <math.h>
    double remainder (double x double y);
    float remainderf (float x float y);
    double remquo (double x double y int *quo);
    float remquof (float x float y int *quo);
     

    DESCRIPTION

    remainder (,);
    remainderf (,);
    remquo (,);
    and remquof ();
    return the remainder Fa r := Fa x - Fa n*y where Fa n is the integer nearest the exact value of -words Fa x Ns / Ns Fa y ; moreover if \*(Ba Fa n - Fa x No / Fa y No \*(Ba = 1/2 then Fa n is even. Consequently the remainder is computed exactly and \*(Ba Fa r \*(Ba \*(Ba Fa y \*(Ba/2 But attempting to take the remainder when Fa y is 0 or Fa x is is an invalid operation that produces a .

    The remquo ();
    and remquof ();
    functions also store the last k bits of Fa n in the location pointed to by Fa quo , provided that Fa n exists. The number of bits k is platform-specific, but is guaranteed to be at least 3.
