The polar(z) calling sequence converts the complex-valued expression z to its representation in polar coordinates.

The expression is represented as polar(r, t) where r is the modulus and t is the argument of the complex value of the expression.

This function can also be invoked as a convert function: convert(z, polar). See convert/polar .
