I.e. use a short to hold an unsigned byte, use a long to hold an unsigned int. (And use a char to hold an unsigned short.) Yeah, this kinda sucks because now you're using twice as much memory, but there really is no other solution. (Also bear in mind, access to longs is ...

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. ...
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 '...
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...
"in that case" meaning the case when 65536 was equal to INT_MAX, then (65535 + 3) most definitely would overflow, and definitely be undefined behavior. The particular form of the manifestation of the undefined behavior, would be different matter, if that's what you mean. ...
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.) ...
2^31-2 doesn't fit in long on 32 bits CPU. On my Linux box, uid_t is an unsigned integer (32 bits unsigned integer). Why not using "unsigned int"? chown prototype: intchown(constchar*path,uid_towner,gid_tgroup); MemberAuthor ...
You will notice that the functions actually return a long for unsinged integers, and an integer for shorts, this is because we can't store a large unsigned int in a java int. You may also be interested to know that byte's, short's, and int's are all actually stored using 4 bytes ...
