Complex parts: Abs(z) (∣z∣\left|z\right|), the complex sign Sign(z) (sgn⁡(z)\operatorname{sgn}(z)), equal to z/∣z∣z/|z| for z≠0z \ne 0; the real-valued sign extension Csgn(z) (csgn⁡(z)\operatorname{csgn}(z)); the absolute value of a real number RealAbs(x) (∣x∣\left|x\right|), Re(z) (Re⁡(z)\operatorname{Re}(z)), Im(z) (Im⁡(z)\operatorname{Im}(z)), the argument Arg(z) (arg⁡(z)\arg(z)) and the complex conjugate Conjugate(z) (z‾\overline{z}).
