NAME
       flmin,  flmax,  ffrac,  dflmin,  dflmax, dffrac, inmax - return extreme
       values

SYNOPSIS
       function flmin()

       function flmax()

       function ffrac()

       double precision function dflmin()

       double precision function dflmax()

       double precision function dffrac()

       function inmax()

DESCRIPTION
       Functions flmin and flmax  return  the  minimum  and  maximum  positive
       floating point values respectively.  Functions dflmin and dflmax return
       the minimum and maximum positive double precision floating  point  val‐
       ues.  Function inmax returns the maximum positive integer value.

       The functions ffrac and dffrac return the fractional accuracy of single
       and double precision floating point numbers respectively.  This is  the
       difference between 1.0 and the smallest real number greater than 1.0.

       These  functions  can be used by programs that must scale algorithms to
       the numerical range of the processor.
