numf is a number formatter. It formats the numbers provided to it.

Current formats are:

  • Hexadecimal
  • Binary
  • Octal
  • Decimal
  • Base32
  • Base64
  • Raw

numf also has the option of prepending a prefix for the formats, such as 0x for hexadecimal. Numbers may also be provided from the stdin. See --help flag for more information.
