[⧼Purge⧽ Template:Digit as int/doc]

The {{digit as int}} base conversion template converts a single character digit into an integer digit = index + offset, where index is the character index (0-indexed) of character digit within an optionally provided conversion string which defaults to

0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz

if character digit is within the conversion string, otherwise offset is returned as the integer digit.

Usage

{{digit as int|single character digit (default 0)|integer offset (default 0)|optional conversion string}}

Valid input

  • First argument: single character digit (default 0, i.e. zero)
  • Second argument: integer offset (default 0)
Negative offset is used to get negative integer digits for balanced numeral systems (e.g. balanced ternary).
  • Third argument: Conversion string of characters with default value
0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz
