I would like to decide how many numbers will be behind the decimal point.
For example I have got:  int n1=1,    int n2=3              n1/n3;
What do I do to get only 2 numbers behind the decimal point  :  0,33   or exactly 3 numbers : 0,333  etc.  ?

If you want it rounded to 3 decimal places, use: Math.Round(n1/n3, 3);

If you want it *truncated* to n decimal places, multiply by 10^n, call Math.Truncate, then divide by 10^n
