Questions tagged [integer]

Common datatype in many programming languages for representing both negative and non-negative whole numbers. Use this tag for questions about using, storing, or manipulating integers. For 64-bit integers, use the [long-integer] tag instead.

An integer is a whole number that can be negative, positive, or zero. For example, -2, -1, 0, 1, 2. In many programming languages, the integer data type is commonly represented as 32-bits, but may also be 64-bits (Usually referred to as the Long data type).

For 32-bit integers:

  • The signed range is : -2147483648 to 2147483647.
  • The unsigned range is : 0 to 4294967295.

For 64-bit integers:

  • The signed range is : -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807.
  • The unsigned range is : 0 to 18,446,744,073,709,551,615.

Is there a way to simulate integer bitwise operations for _m256 types on AVX?

I have a boolean expression that I have managed to implement in SSE2. Now I would have liked to try implementing it in AVX exploiting an additional factor 2 in parallelism increase (from 128 bit SIMD type to 256). However, AVX does not support…

Why is float.MaxValue 0xFF 0xFF 0x7F 0x7F and not 0x7F, 0xFF, 0xFF, 0xFF like ints?

I guess this needs little extra information. But, why is it that way? (This assumes the 23 bit float type is base on IEEE 754 32 bit binary floating point, and Little Endianness.) In 32bit ints it's pretty straightforward, since: int.MaxValue =…
