    128-bit signed integer.

  • int16

    16-bit signed integer.

  • int32

    32-bit signed integer.

  • int64

    Natural numbers are those used for counting and ordering. Some definitions, like ISO 80000-2 begin the natural numbers with 0. But in this definition, natural numbers start with 1. For integers that start at 0, see uint.

  • negeven

    Negative even number.

  • negint

    Negative integer (-1, -2, ...).

  • negodd

    Negative odd number.

  • nonnegint

    Non-negative integer (0, 1, 2, ...) [DEPRECATED].

    This schema is DEPRECATED. Please use the new name uint.

    See also posint for integers that start from 1.

  • odd

    Odd number.

  • poseven

    Positive even number.

  • posint

    Positive integer (1, 2, ...).

    Zero is not included in this schema because zero is neither positive nor negative. See also uint for integers that start from 0.

  • posodd

    Positive odd number.

  • uint

    Non-negative integer (0, 1, 2, ...).

    See also posint for integers that start from 1.

  • uint128

    128-bit unsigned integer.

  • uint16

    16-bit unsigned integer.

  • uint32

    32-bit unsigned integer.

  • uint64

    64-bit unsigned integer.
