How to use the number "pi" in Visual Basic?

Hi everyone,

I have to pass numbers expressed in radians to numbers expressed in degrees. It simply consist of multiplying by (180/pi). You know, pi=3,1416.... However, when I try it, visual basic doesnt recognize the number pi. (You can try to do the following sentence on the inmediate window: a=2*pi; ?a; return). I dont undestand it because I have looked the subject up the vb help and it tells me the same solution: I simply must do the product between the number and (180/pi).

Can anyone help me?

Thanks,

Cris
