Bug in converting complex numbers?

[blevita]

Hi

I have tried to convert a complex number in the style of 100*exp(60 Deg)
Usually they should be converted to something like:

100*(cos(60)+i*sin(60)) = 50+86.6*i

But the Prime converts the expression 100*exp(60 Deg) to -95.24 - 30.48*i
This is a strange behaviour to me.

Do i have to enter the complex number in an other way?
Or is this a software bug?
