Template:Digit as char/doc

This documentation subpage contains instructions, categories, or other information for Template:Digit as char. [<Edit> Template:Digit as char]

[⧼Purge⧽ Template:Digit as char/doc]

The {{digit as char}} base conversion template converts a given digit (as integer) into the 0-indexed character (with index = digit - offset) from an optionally provided conversion string which defaults to

0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz

if 0 ≤ digit - offset < length of string, otherwise digit is returned as integer surrounded by : (colon).

Usage

{{digit as char|digit as integer (default 0)|integer offset (default 0)|optional conversion string}}

Valid input

• First argument: digit (default 0) as integer, where digit ≥ offset

Negative integer digits are used with balanced numeral systems (e.g. for balanced ternary numeral system).

• Second argument: offset as integer (default 0)

• Third argument: String of characters (conversion string) with default value

0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz
