How to do polar form like mathcad?

Hi,
I have just started to use Smath and am liking it so far.
I could not figure out how to enter values in polar form with its angle? say 100/_60deg, i.e. a magnitude of 100 and a degree of 60.
On Mathcad the polar operator is in operator -> engineering menu. I can't find similar in smath but everything else I am at home with.
I can see there is a polxy function but it is not quite the same?
Thanks

If I dont put the degree sign it will return -95.24 -30.48i which is a different result. Thanks

Plot the circle as well.

Thanks! that works well. How would I convert from polar to rectangular but using the variable instead? say I have this: pol(m,a):= m.exp(a.pi/180*i) V:=pol(1,10) = 0.9841 + 0.1736*i I:=V/200 = 0.0049 + 0.0009*i I want to display I in a polar form. I can use xypolto but not so convenient. How do I do xypol2(I) = ? Edited by user 29 May 2022 07:54:03(UTC)
