WebItems are stored in files as a sequence of bytes, so if you're worried about disk space you should use bytes. Items are processed by your CPU in 32- or 64-bit integers (depending on your processor) so any item that's less than that amount will be "upgraded" to a 32- or 64-bit representation for runtime computation. – Jake Feb 27, 2010 at 7:33 1 WebMar 25, 2024 · C# integers Integers are a subset of the real numbers. They are written without a fraction or a decimal component. Integers fall within a set Z = {..., -2, -1, 0, 1, 2, ...}. Integers are infinite.
