Refactor the\ninitializations so that mantissa and exp have separate declarations and\nsign gets initialized later.\n\nIn addition (and due to the nature of the cleanup), fix a sign-extension\nbug where, float32 would get bitwise anded with ~BIT(31)\n(which is 0xFFFFFFFF7FFFFFFF) which corrupted the exponent.",
