Answer 1

Depends on what your number represents and how you want to manage the values: is it a currency, do you need rounding or truncation, do you need this rounding only for display?

If for display consider formatting the numbers are x.ToString("")

If it is just rounding, use Math.Round overload that requires a MidPointRounding overload

If you get your value from a database consider casting instead of conversion: double value = (decimal)myRecord["columnName"];
