Math.Pow can't handle fractions ?

Accepted answer

Try this
1:
double dd = Math.Round(((double)1 / (double)3),5);
2: or
decimal dd = Decimal.Round((decimal)1 / (decimal)3,5);

varX = Math.Pow(varx, dd);

Also works!
I think it is more "correctly" than Froglegs round workaround.
Thanks

Rather than use casts, you can force double arithmetic like this:

1.0/3 or 1D/3

or decimal arithmetic with:

1M/3

As long as at least one operand is of type double or decimal, then this will avoid integer arithmetic from being used.

You are too fast. I edit to include double

Instead of decimal I had to set it to double.
And it WORKS! O_o
It can't calculate with endless numbers, can it?
Many thanks
