Synopsis
#include <flint/fexpr_builtin.h>AbsSignCsgnRealAbsReImArgConjugateComplex parts: Abs(z) (\left|z\right|), the complex sign Sign(z) (\operatorname{sgn}(z)), equal to z/|z| for z \ne 0; the real-valued sign extension Csgn(z) (\operatorname{csgn}(z)); the absolute value of a real number RealAbs(x) (\left|x\right|), Re(z) (\operatorname{Re}(z)), Im(z) (\operatorname{Im}(z)), the argument Arg(z) (\arg(z)) and the complex conjugate Conjugate(z) (\overline{z}).
