- INTEGER FUNCTION
- IEEECK( ISPEC, ZERO, ONE )
- INTEGER ISPEC
- REAL ONE, ZERO
PURPOSE
IEEECK is called from the ILAENV to verify that Infinity and possibly NaN arithmetic is safe (i.e. will not trap).ARGUMENTS
- ISPEC (input) 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 (input) REAL
- Must contain the value 0.0 This is passed to prevent the compiler from optimizing away this code.
- ONE (input) 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 Return if we were only asked to check infinity arithmetic
