     NAME
          fabs, fmod, floor, ceil - absolute value, remainder, floor,
          ceiling functions

     SYNOPSIS
          double floor(double x)

          double ceil(double x)

          double fabs(double x)

          double fmod(double x, double y)

     DESCRIPTION
          Fabs returns the absolute value |x|.

          Floor returns the largest integer not greater than x.

          Ceil returns the smallest integer not less than x.

          Fmod returns x if y is zero, otherwise the number f with the
          same sign as x, such that x = iy + f for some integer i, and
          |f| < |x|.
