In many circumstances it helps a lot to get a string formatted in a specific way straight during the conversion stage from an int of float, instead of going through a routine to format the string after the fact. C# has some nice built-in format strings just for that, which weren't exposed in Playmaker - so far
A couple good examples of use:
-Leading zeroes on an int-converted variable. Suppose you have values like 20, 140 and want to see them shown as 0020, 0140, etc. To do that you'd use Format = "0000" or "D4"
- Format in percentage notation a float number, for instance, convert 0.2 to 20% in a statistics display. For that you'd use format = "P2".

If it's an existing project don't worry, these actions are compatible with any existing data, if the 'format' field is set to null it performs the original, no-format behavior. Hope you find it of use, enjoy!
