Template:Octal/doc

The {{Octal}} template makes it easy to convert decimal numbers (base 10) into octal (base 8) and formats them according to a variety of common notations.

Usage

This template has one mandatory parameter: the decimal number that is to be converted to octal (represented below as n). It may be supplied as the first unnamed/positional parameter ({{Octal|n}}), or as the value of the named value ({{Octal|value=n}}) or 1 ({{Octal|1=n}}) parameters.

Basic examples

• {{Octal|4632}} → 110308
• {{Octal|value=81681.125}} → 237421.18
• {{Octal|1=-51985}} → -1454218

Formatting

This template also provides an optional second parameter which controls the formatting of the conversion output, with several § Notation keywords that correspond to various alternate notations for octal numbers other than the default subscripted Arabic numeral 8 (n8). The keywords may be defined as an unnamed/positional second parameter ({{Octal|n|formatting_keyword}}) or as the value of the named affix ({{Octal|n|affix=formatting_keyword}}) or 2 ({{Octal|n|2=formatting_keyword}}) parameters.

Both of the suffix notations, i.e. the default formatting and the oct keyword, provide the added benefit of displaying a tooltip that reads "octal number (base 8)" to further assist in identifying non-decimal numbers within dense prose content.

Notation keywords

• Default formatting (parameter empty or undefined/absent keyword): Subscripted serif 8 suffix (8)

  {{Octal|4632}} → 110308

• oct: Subscripted serif oct suffix (oct)

  {{Octal|4632|oct}} → 11030oct

• o: Lowercase o prefix (o)

  {{Octal|4632|o}} → o11030

• 0o: Arabic numeral 0 with lowercase o prefix (0o)

  {{Octal|4632|0o}} → 0o11030

• \ / backslash / bs / revsol / rs: Reverse solidus (backslash) prefix (\)

  {{Octal|4632|\}} → \11030

• digit / no / none: Unformatted output

  {{Octal|4632|none}} → 11030
