Output Format for double

I've simple question on formatting. I've a double returning a number that will always be a multiple of 0.5. (e.i. the number can be 125.5, 125, 160, 171.5) In my output window I am currently printing something like this:

double number;
(number).ToString("###0.0");

However, in the case my number is an integer, such as 125, this returns a value of 125.0, which I would like the number to be printed out as 125, whilst keeping the capability of printing out the decimal number in case the double number was for example 126.5.

Does anybody know how I can do this? Thanks!

In C# Use String.Format

String.Format("{0:0.00}", 123.4567);                    // "123.46"
String.Format("{0:0.00}", 123.4);                       // "123.40"
String.Format("{0:0.00}", 123.0);                       // "123.00"

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

String.Format("{0:00.0}", 123.4567);                    // "123.5"
String.Format("{0:00.0}", 23.4567);                     // "23.5"
String.Format("{0:00.0}", 3.4567);                      // "03.5"
String.Format("{0:00.0}", -3.4567);                     // "-03.5"

String.Format("{0:0,0.0}", 12345.67);                   // "12,345.7"
String.Format("{0:0,0}", 12345.67);                     // "12,346"

String.Format("{0:0.0}", 0.0);                          // "0.0"
String.Format("{0:0.#}", 0.0);                          // "0"
String.Format("{0:#.0}", 0.0);                          // ".0"
String.Format("{0:#.#}", 0.0);                          // ""

String.Format("{0:0.00;minus 0.00;zero}", 123.4567);    // "123.46"
String.Format("{0:0.00;minus 0.00;zero}", -123.4567);   // "minus 123.46"
String.Format("{0:0.00;minus 0.00;zero}", 0.0);         // "zero"

Try using this format string:

"###0.#"

I'm assuming from your capitalisation of ToString that this relates to C#.
