Different format for whole numbers and decimal

is there a way of formatting a string to show whole numbers of a decimal number if it follows 00.

example show 10 if number is 10.00. but show 10.2 if number is 10.2

this is for c#, asp.net

From stackoverflow

• In .NET:

  if (Math.Floor(d) == d)
      return d.ToString("0");
  else
      return d.ToString();
  

• Of course there is:

  (if (!= 0 (- (string-to-number x) (floor (string-to-number x))))
      (number-to-string (string-to-number x))
      x)
