The functions described here are not found on all versions of UNIX, e.g., HP-UX.
nint returns the integer nearest to x.
anint returns the nearest whole number to x.
aint returns the nearest whole number y to x with |y| <= |x|.
usleep sleeps for a given number of microseconds, usec, or until awakened by a signal.
Return values for nint, anint, and aint are described above. usleep always returns 0.
nint can generate integer overflows with undefined results.
aint and anint are implemented using fmod.
