Overview
remainder(), remainderf(), remainderl(), remquo(), remquof(), and remquol() return the remainder r := x - n∗y where n is the integer nearest the exact value of x/y; moreover if Fan - x/y = 1/2 then n is even. Consequently the remainder is computed exactly and Far
Fay/2. But attempting to take the remainder when y is 0 or x is is an invalid operation that produces a .
The remquo(), remquof(), and remquol() functions also store the last k bits of n in the location pointed to by quo, provided that n exists. The number of bits k is platform-specific, but is guaranteed to be at least 3.
