Arg

Arg[z] gives the argument of the complex number z.

Mathematical function (see Section A.3.10).

Arg[z] is left unevaluated if z is not a numeric quantity.

Arg[z] gives the phase angle of z in radians.

The result from Arg[z] is always between and .

Arg[z] has a branch cut discontinuity in the complex z plane running from to .
