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. WebNote that because of the possibilities of signed 0 and NaNs, the expression "x < 0.0" does not give the same result as signbit in all cases.
