Questions tagged [primitive]

A primitive type is a data type provided by a programming language as a basic building block.

The actual range of primitive data types that is available is dependent upon the specific programming language that is being used. For example, in C, strings are a composite but built-in data type, whereas in modern dialects of BASIC and in JavaScript, they are assimilated to a primitive data type that is both basic and built-in.

Classic basic primitive types may include:

  • (character, char)
  • (integer, int, short, long, byte) with a variety of precisions
  • number (float, double, real, double precision)
  • number (fixed) with a variety of precisions and a programmer-selected scale
  • , logical values (true, false)
