Questions tagged [uint]

is a type of variable and is used to store the equivalent of a mathematical non-negative integer

Due to the limited amount of memory a computer can handle, uint can represent just a subset of positive integers.

C++11 uint types vs u_int

I just stumbled upon the type u_int8_t because it did not compile in Windows+MinGW (but compiled fine under Linux). According to this site the C++11 standard defines the type uint8_t. I just used the latter and everything worked. The questions that…

Use uint or int

Definitely, I know the basic differences between unsigned integers (uint) and signed integers (int). I noticed that in .NET public classes, a property called Length is always using signed integers. Maybe this is because unsigned integers are not CLS…

What is the best way to combine two uints into a ulong in c#

What is the best way to combine two uints into a ulong in c#, setting the high/low uints. I know bitshifting can do it, but I don't know the syntax, or there maybe other APIs to help like BitConverter, but I don't see a method that does what I want.
