I tried to convert dec to hex. For example convert 255 to hex.
opa = 255.ToString("X");
gives me error: error: invalid suffix "ToString" on floating constant
I spent lots of time to convert, but couldn't find right way.

2The question you linked is `C#`. Do you want `C#` to `C`? – merlin2011 Jul 01 '14 at 23:08

4Then copying code from a question on C# won't work; they're completely different languages. – IMSoP Jul 01 '14 at 23:10

You need `sprintf()`. – Crowman Jul 01 '14 at 23:10

@Merlin2011 Editing a comment to say something completely different like that is very confusing. It will also stop anyone being notified of your new question. – IMSoP Jul 01 '14 at 23:12

@Ben I read that one, but it only outputs as hex, I want to assign that value as hex to another variable. – user3763437 Jul 01 '14 at 23:14

The question doesn't even make sense. 255 is a *number*, and numbers aren't decimal or hexadecimal. They're just numbers. – Kerrek SB Jul 01 '14 at 23:16

You're asking about the wrong language. C does not support the dot operator on integers. To do this in C, you need to print it to a string like so.
char numstr[10];
sprintf(numstr, "%X", 255)

On a side note, numstr is string type, but I wanted it to be integer type, so I can do calculations with it. – user3763437 Jul 01 '14 at 23:29

2If it's an integer, it's an integer. Whether it's dec of hex is just how you print it. – Phonon Jul 01 '14 at 23:44
