SYNOPSIS

   #include <math.h>

   double remainder(double x, double y);
   float remainderf(float x, float y);
   long double remainderl(long double x, long double y);

DESCRIPTION

remainder produces the remainder when the first argument, x, is divided by the second argument, y. Both arguments are assumed to be exact, and the division is performed exactly. The remainder is computed using a rounded integer quotient. If the fractional part of the quotient is 0.5, the quotient is rounded to an even value.

The function name remainderf should be used for float arguments, and remainderl for long double arguments. Alternately, if the header file tgmath.h is included, remainder may be used with any numeric argument type.

RETURN VALUE

remainder returns the remainder resulting from division of x by y, if it is defined and representable.
