[RESOLVED]Exp function

Hi;
I'm using Exp fuction to calculate e^(Pi*Tan(fi*Pi)) like below

c=Exp(Pi*Tan(fi*Pi))

but there is problem on result. Where is my mistake is it wrong functions or i'm using function wrong.
thanks

Don't leave us hanging what was the answer?

If you are using VB to solve this, don't forget that all trig-functions run on radians not degrees!
I'd bet that this is your problem!
