There are four type modifiers in C++: short long signed unsigned Here's a brief summary: Data TypeSize (in Bytes)Meaning signed int4Used for integers (equivalent toint). unsigned int4Can only store non-negative integers. short2Used for small integers. ...
The C standard defines this situation as undefined behavior (meaning that anything might happen). In practice, this usually translates to a wrap of the value if an unsigned integer was used and a change of the sign and value if a signed integer was used....
In languages like C and C++, there exist a variety of sizes of integers, char, short, int, long. (char isn't really an integer, but you can use it like an integer and most people use it in C for really small integers.) On most 32 bit systems, these correspond to 1 byte, 2 by...

I see that #488 was closed as completed. However, it doesn't look unsigned int works. The below shader results in the following error message when unsigned is used with int: shader.hlsl(26): error 20001: unexpected identifier, expected '...
When an integer is signed, one of its bits becomes the sign bit, meaning that the maximum magnitude of the number is halved. (So an unsigned 32-bit int can store up to 232-1, whereas its signed counterpart has a maximum positive value of 231-1.) ...
Well, in that case I suggest you adopt Pavel A's suggestion. Do you mean I have to assign my variable to unsigned int variable and then I have to pass it to the function? Pavel A suggested that you pass the member of the union that is an unsigned int. Changes to the value of thi...
Hmm. I take that back. I don't think any of this really belongs inObjects/longobject.c. Right now that module contains entirely portable C code that knows almost nothing about operating systems. In particular, the knowledge that -1 has special meaning doesn't really have a place in the ...
Well yeah, if we're talking about strictly the data and memory then my statement is entirely incorrect. I was viewing it as finding out if an int in memory is signed or unsigned -through- the program that is using it, so I guess there's just a bit of a misunderstanding of what firs...
I found myself today needing to deal with unsigned integers, and shorts in java. In Java there is no unsigned keyword like in C, or other languages. All primitives are signed (meaning they can hold negative values). So I came up with two functions for converting the unsigned byte arrays...
