Your inputs

Start with an example

Example result

Convert to octal, pad with leading zero digits and append one null byte. The terminator is part of the selected width.

Decimal 512 becomes octal 1000, or 00000001000 followed by null in a 12-byte field.

POSIX octal form only. Values that need GNU/base-256 extension encoding are rejected.
