Trailing zero on decimal

Question

I have a string which looks like this 512.3 is there a way to add a trailing zero so it looks like this 512.30

Just to clarify (sorry I didn't know there where different ways etc.)

My string is an amount which is passed so changes all the time I only need the trailing zero on amounts like 512.3, 512.4,512.5 etc. as some of my amounts will pass values like 512.33 and 512.44 and so on

Thanks

Jamie

Answer 1

float.Parse("512.3").ToString("0.00");

It would give the number with two decimal digits.

Answer 2

You're going to want to use String.Format or some derivation thereof, and the format string will look like

myString = String.Format("{0:F2}",myObject);

Also note that format strings can be used in the .ToString("F2") method (notice I included the format string F2 inside there already.

See the MSDN links above for a more thorough and definitive explanation.
