I've changed from double to decimal calculations but I can't find a math
library for decimal (mainly for sqrt),
Thanks Maor
 
Since Math.Sqrt only uses double you will have to cast it to and from
double.

decimal d = 0.0000000000000000000000000002m;
decimal e = (decimal)Math.Sqrt((double)d);

// e == 0,000000000000014142135623731

Hi Maor,

I'm affraid that Math.Sqrt is only choice...
and it works with double numbers only.
You can write your own DecimalSqrt function:

public static decimal Sqrt(decimal val) {
return new Decimal(Math.Sqrt((double) val));
}
