"Big Math"[1] : Solver Foundation and F#

It would be powerful for 'big math' users of Powershell if we could integrate F# and Microsoft's Solver Foundation into Powershell 3.0. Microsoft's Solver Foundation provides for "Programming in the Optimization Modeling Language (OML), in C# imperatively, in F# functionally, or in any .NET language".  
So will it work with a DLR language like Powershell 3.0 Beta?  I don't know yet but here is some exploratory script.:

"Big Math"[0] : [BigInt] to the rescue!

 BigInt to the  rescue.  Only with .NET 4.0. From PS 3.0 Beta:


Normally:


${2^1023}=[math]::POW(2,1023)
${2^1023}
8.98846567431158E+307
${2^1024}=[math]::POW(2,1024)
${2^1024}
Infinity
${2^1023} * 1.99999999999999988
1.79769313486232E+308
$AMAX=${2^1023} * 1.99999999999999988
[Double]::MaxValue
1.79769313486232E+308
[Double]::MaxValue - $AMAX
0


...and thus integer factorial is limited to 170:
