Math.Round vs String.Format

Question

I need double value to be rounded to 2 digits. What is preferrable?

String.Format(\"{0:0.00}\", 123.4567);      // \"123.46\"
Math.Round(123.4567, 2)                 


        

Answer 1

That depends on what you want to do with it.

String.Format will return a string, Math.Round(double) will return a double.
