ieeeck

Functions

INT ieeeck(
    const INT   ispec,
    const float zero,
    const float one
);

INT ieeeck(const INT ispec, const float zero, const float one)

IEEECK is called from the ILAENV to verify that Infinity and possibly NaN arithmetic is safe (i.e.

will not trap).

Parameters

in

ispec

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

in

zero

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

in

one

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