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 _f_l_m_i_n and _f_l_m_a_x  return  the  minimum  and  maximum  positive
       floating point values respectively.  Functions _d_f_l_m_i_n and _d_f_l_m_a_x return
       the minimum and maximum positive double precision floating  point  val‐
       ues.  Function _i_n_m_a_x returns the maximum positive integer value.

       The functions _f_f_r_a_c and _d_f_f_r_a_c 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.
