stdio: Fix printing 0.0
We were relying on FE_DIVBYZERO being turned off when printing "%f", +-.0 Avoid the whole issue by looking at the sign-bit (in a rough approximation). Note that we do not handle gracefully: printf ("\n%llf\n", -0.0); printf ("\n%llf\n", 0.0); nor %Lf for both when NOT cast to long double. Avoiding an FPE due to broken numbers like these does not make sense to me. Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
