Please help with Color info

Question

Simple question, I hope.
In the string:
private Color purple = new Color(0.5f, 0.0f, 0.5f);
Where do I get the information on this in the docs? I want to know what the "f" stands for in the arguments to get a good understanding of this code. I searched through the color docs and could not find what I need to know. Can't find a reference to this. I thought I might not be looking in the correct area.
Thanks, .......daljaxon

Answer 1

f stands for float. If you create a number literal 0.5, it defaults to be a double. You put a f (or F works too, I think) after it to indicate you mean it to be a float. The same thing happens for int/long. 2 is int 2, 2L is long 2. It's also similar, although probably more efficient, to this: (float)0.5 or (long)2. It's just a function of the language, nothing to do with the Color class or any other class.
