WebC++ - signbit () Function. The C++ signbit () function returns true if the given argument is negative, else returns false. This can be also applied to infinity, NaN and zero (if zero is unsigned, it is considered positive). Websignbit () is a generic macro which can work on all real floating- point types. It returns a nonzero value if the value of x has its sign bit set. This is not the same as x < 0.0, because IEEE 754 floating point allows zero to be signed. The comparison -0.0 < 0.0 is false, but signbit (-0.0) will return a nonzero value.
