Question: How to convert a complex number to its exponential form with a command

I was about to convert -1 to exp(I*Pi).

First try by intuition

convert(-1, exp);

False intuition. Next try by right click on -1 and consulting the context pannel: -> nothing that rings a bell

Entering a complex number 0.5000000001 + 0.8660254037*I to see if that changes something

-> something but no exponential form

Next: AI assitant

->   OK, I know this. -> refine query

Polar, of course!

convert(-1, polar);
                          polar(1, Pi)

Not what I want. Maybe

convert(convert(-1, polar), exp);

Next -> Ask for help in MaplePrimes whether there is a command

Please Wait...
