Given the string "268179", is there any built in methods that could change this to 2.68 in C#

Question

Looking to convert this to a string value of 2.68. I have a way to parse it out but was wondering if there was some built in functionality in the framework to do this.

Answer 1

Why not turn it into a number, divide by 100,000 like Dominic suggested and then format the number back into a string with the appropriate number of decimal places?

Answer 2

Untested, uing the builtin function Int32.Parse:

string convert_so_1272865_v1(string s){
  return ((Int32.Parse(s)/1000)/100.0).ToString();
}

And a version without any parsing:

string convert_so_1272865_v2(string s){
  return s.SubString(0,1) + "." + s.SubString(1,2);
}

Answer 3

Assuming that the number is just a fixed point fixed width number with 1 digit left and 5 digits right of the decimal point, try (Decimal.Parse("268179") / 100000D).Round(2)
