Decimal Formatting in C#

Question

I want a function that shows at most N decimal places, but does not pad 0's if it is unnecessary, so if N = 2,

2.03456 => 2.03
2.03 => 2.03
2.1 => 2.1
2 => 2

Every string formatting thing I have seen will pad values like 2 to 2.00, which I don't want

Answer 1

How about this:

// max. two decimal places
String.Format("{0:0.##}", 123.4567);      // "123.46"
String.Format("{0:0.##}", 123.4);         // "123.4"
String.Format("{0:0.##}", 123.0);         // "123"

Answer 2

Try this:

string s = String.Format("{0:0.##}", value);
