M Morten Wennevik Jan 21, 2004 #2 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)); } Regards Marcin
