Signed integers support only up to 64 bits
WebSep 29, 2024 · Starting in C# 9.0, you can use the nint and nuint keywords to define native-sized integers. These are 32-bit integers when running in a 32-bit process, or 64-bit integers when running in a 64-bit process. They can be used for interop scenarios, low-level libraries, and to optimize performance in scenarios where integer math is used extensively. WebAug 19, 2024 · In this article. Three classes of data types were introduced for 64-bit Windows: fixed-precision data types, pointer-precision types, and specific-pointer-precision types. These types were added to the development environment to allow developers to prepare for 64-bit Windows. These types are derived from the basic C-language integer …

WebNov 9, 2013 · Thanks for the input! I was asking as I was looking to store a lot of values that ranged from 0 to 2,851,254,831 and this is just north of the upper limit for signed 32 bit integers - 2,147,483,547. An unsigned 32 bit integer would store this just fine, as the maximum is 4,294,967,295. By storing as a signed Int32 and then converting out when I ... WebMay 2, 2024 · Typically, computers store integers in their CPU’s registers (which nowadays are usually 32 or 64 bits wide), or in register-sized chunks of memory. This leads to the minimum and maximum values you might be familiar with. For example, a 32-bit signed integer can hold values from -2,147,483,648 to 2,147,483,647.
