Help! Where has Math.PI gone in F# CTP?

Question

I'm just trying to do simple scripting with F#, and Math.PI seems to have 'disappeared'. I've referenced FSharp.PowerPack.dll, but still can't find it.

Answer 1

The constant pi is System.Math.PI, if you want to use, Math.PI just open System, in your fsharp file:

open System
Math.PI
