NAME
       SLAMCH - determine single precision machine parameters

SYNOPSIS
       REAL FUNCTION SLAMCH( CMACH )

	   CHARACTER CMACH

PURPOSE
       SLAMCH determines single precision machine parameters.

ARGUMENTS
       CMACH   (input) CHARACTER*1
	       Specifies the value to be returned by SLAMCH:
	       = 'E' or 'e',   SLAMCH := eps
	       = 'S' or 's ,   SLAMCH := sfmin
	       = 'B' or 'b',   SLAMCH := base
	       = 'P' or 'p',   SLAMCH := eps*base
	       = 'N' or 'n',   SLAMCH := t
	       = 'R' or 'r',   SLAMCH := rnd
	       = 'M' or 'm',   SLAMCH := emin
	       = 'U' or 'u',   SLAMCH := rmin
	       = 'L' or 'l',   SLAMCH := emax
	       = 'O' or 'o',   SLAMCH := rmax

	       where

       eps   = relative machine precision
	     sfmin  =  safe  minimum,  such  that  1/sfmin  does not overflow base  = base of the
	     machine prec  = eps*base t     = number of (base) digits in the mantissa rnd   = 1.0
	     when  rounding  occurs  in  addition,  0.0 otherwise emin	= minimum exponent before
	     (gradual) underflow rmin  = underflow threshold -	base**(emin-1)	emax   =  largest
	     exponent before overflow rmax  = overflow threshold  - (base**emax)*(1-eps)
