Euler's formula in F# : #2

In last year, I wrote Euler's formula in F#. In this article, I used C# classes in System.Numerics namespace. At this time, i write again, with using F# PowerPack.
Microsoft (R) F# 2.0 Interactive build

val euler_formula : Complex = -1r-1.22460635382238e-16i
But this also becomes inexact result of floating-point.
