Subject: FE Exception triggered by comparison
What comparison of FP numbers trigger invalid operation exceptions?
Does a comparison like
if (x != x)
{
/* get to here if x == NaN *
}
which tests for a NaN cause an invalid operation if given an sNaN?
Even reading the standard numerous times and I am not any wiser.
Thanks - Damian
