FLMIN(3F)           UNIX Programmer's Manual            FLMIN(3F)



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 values.  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 accu-
     racy 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.
