Questions tagged [int]

A data type that represents an integer. An integer is a whole number that can be negative, positive, or zero. (i.e. ...-2, -1, 0, 1, 2...) Use this tag for questions about using, storing, or manipulating integers.

int is a data type that represents an integer (a whole number - not a fraction).

int data types may vary based on:

  • the number of bits used to represent them - 16, 32, etc.
  • whether they allow both negative and positive values (signed integers) or only positive (unsigned integers).

In many (but not all) languages, integers are limited to a specific range due to the way they are stored - for instance, an ISO C 32-bit signed integer can store values from −2,147,483,648 to +2,147,483,647 (-2³¹ to 2³¹-1).

This keyword is often used in C-like languages (including C, C++, Golang, etc.)

Using Int type vs. Integral constraint. Advantage?

Consider these (more or less) equivalent type signatures: f1 :: [a] -> Int -> a f2 :: Integral b => [a] -> b -> a f2 is more general than f1, and that is a big advantage, but is there an advantage of f1 over f2? It seems that in the solutions to…

Sorting 32 bit ints is as fast as sorting 64 bit ints

Here are things I believe are facts: Quick sort should be fairly cache friendly. A cache line of 64 bytes can contain 16 32-bit ints, or 8 64-bit ints. Hypothesis: Sorting a vector of 32-bit integers should be faster than sorting a vector of…

As the title explains, I am looking to generate a series of random short values. Because there is no Random.nextShort() function, the easiest way to do what I want seems to be to cast integers to short, using: Random rand = new Random(int…
