I cannot find any check for "Floating point expressions shall not be compared using either the == or != operators." - is there one?
My company's standards justify this rule with:
"Comparing floating point expressions for equality or inequality is a famous source of well-documented software system failures."
It seems we don't have it. But I thought every compiler would have such warning. I.e. gcc has
-Wfloat-equal. Do you feel it's acceptable to use gcc for this (and possibly get various other warnings)?
