| **Description:**    | Numbers without a fractional component (positive, negative, and 0)                                                                                        |

| **Literal syntax:** | A decimal, hex, octal, or binary numeric value without a decimal place. E.g., `-100`, `0`, `50`, `+50`, `0xff` (hex), `0o234` (octal), `0b10101` (binary) |

## Additional Language Notes

- Integers are internally represented as signed 64-bit numbers with two's-complement arithmetic.

Title: Integer Data Type in Nushell

Summary

This section defines the integer data type in Nushell. Integers are whole numbers (positive, negative, or zero) represented internally as signed 64-bit numbers. The annotation for integers is `int`. Examples of integer literals include decimal, hexadecimal, octal, and binary representations. The `into int` command can be used to cast values to integers.
