/* This code expects correct IEEE rounding behaviour which is not
   always provided.  The source should be built with -ffloat-store.
   A note from the GCC man page:

   -ffloat-store
    Do  not  store floating point variables in registers.  This pre-
    vents undesirable excess precision on machines such as the 68000
    where  the floating registers (of the 68881) keep more precision
    than a double is supposed to have.

    For most programs, the excess precision does only  good,  but  a
    few  programs  rely  on  the precise definition of IEEE floating
    point.  Use `-ffloat-store' for such programs.  */

/* Disable "global optimizations" to avoid optimizer bugs in this file.
   For GCC the file should be compiled with the -fno-gcse option.  Here
   is a note from the GCC man page:

    Note: When compiling a program using computed gotos, a GCC exten-
    sion, you may get better runtime performance if you disable the
    global common subexpression elimination pass by adding -fno-gcse to

/*          Specifies whether proper rounding  ( RND = .TRUE. )  or */
/*          chopping  ( RND = .FALSE. )  occurs in addition. This may not */
/*          be a reliable guide to the way in which the machine performs */
/*          its arithmetic. */

/*  EPS     (output) DOUBLE PRECISION */
/*          The smallest positive number such that */

/*             fl( 1.0 - EPS ) .LT. 1.0, */

/*          where fl denotes the computed value. */

/*  EMIN    (output) INTEGER */
/*          The minimum exponent before (gradual) underflow occurs. */

/*  RMIN    (output) DOUBLE PRECISION */
/*          The smallest normalized number for the machine, given by */
/*          BASE**( EMIN - 1 ), where  BASE  is the floating point value */
/*          of BETA. */

/*  EMAX    (output) INTEGER */
/*          The maximum exponent before overflow occurs. */

/*  RMAX    (output) DOUBLE PRECISION */
/*          The largest positive number for the machine, given by */
/*          BASE**EMAX * ( 1 - EPS ), where  BASE  is the floating point */
/*          value of BETA. */
