Hi,
I'm just wondering what the proper name is for those 1 letter symbols that tell the compiler the datatype of a number?
i.e.:
I'm trying to find a list of all the symbols that I can use, but I'm not sure what they're called.Code:float num = 3.14f;
numeric suffixes seems to be the correctest term I could find. Couldn't find a good link for all of them tho'. Here's a "syntax diagram" for numeric values:

which gives you the ability to make your own table of what they are.

The term "literal suffix" seems to have a higher proportion of relevant hits than any other term I tried.Originally Posted by cpjust
The C++ Standard calls that a "type suffix".

OK thanks.
I'm trying to find out if there's a type suffix for a short?
Not that I'm aware of.
Shorts are just like int, but can't be quite as big [for the pedants: assuming it's not a 16-bit machine where short and int are both 16 bits]

Crap.
The strange thing is, even if I use a cast, it still complains about:
on this line:warning C4244: 'argument' : conversion from 'int' to 'unsigned short', possible loss of data
Why would adding 2 unsigned shorts get converted into an int?Code:obj.SetUnsignedShort( obj.GetUnsignedShort() + static_cast<unsigned short>(1) );
Obviously I can cast the whole thing like this:
But I'm wondering why I need to?Code:obj.SetUnsignedShort( static_cast<unsigned short>(obj.GetUnsignedShort() + 1) );
Strange, but I guess that the return value from GetUnsignedShort() is promoted to int - where you put the cast should make no big difference [at least not unless you have very weird hardware that does math differently than "standard"].Crap.

All calculations are done at at least int width. No matter what kinds of integers you add together, they'll end up an int or bigger.
All the buzzt!
