NAME
       ieeeck.f -

SYNOPSIS
   Functions/Subroutines
       INTEGER function ieeeck (ISPEC, ZERO, ONE)
	   IEEECK

Function/Subroutine Documentation
   INTEGER function ieeeck (integerISPEC, realZERO, realONE)
       IEEECK

       Purpose:

	    IEEECK is called from the ILAENV to verify that Infinity and
	    possibly NaN arithmetic is safe (i.e. will not trap).

       Parameters:
	   ISPEC

		     ISPEC is INTEGER
		     Specifies whether to test just for inifinity arithmetic
		     or whether to test for infinity and NaN arithmetic.
		     = 0: Verify infinity arithmetic only.
		     = 1: Verify infinity and NaN arithmetic.

	   ZERO

		     ZERO is REAL
		     Must contain the value 0.0
		     This is passed to prevent the compiler from optimizing
		     away this code.

	   ONE

		     ONE is REAL
		     Must contain the value 1.0
		     This is passed to prevent the compiler from optimizing
		     away this code.

	     RETURN VALUE:  INTEGER
		     = 0:  Arithmetic failed to produce the correct answers
		     = 1:  Arithmetic produced the correct answers
