Template:Is century/doc

Usage

This template can be used in other templates to check or analyse an input entered in the the form Xth century (ie. the format used in Works by century‎, Births by century‎ and Deaths by century‎).

{{is century|input=|function=}}

The template can be used without named parameters as well. The most basic usage is:

{{is century|}}

Input

The input must be in the form of Xth century or Xth century BCE. The maximum value is 21st century and the minimum value is 20th century BCE. There is no 0th century, so this will not work as an input.

Function

The function must be one of the numbers in this table. This parameter is optional. If not set, function 0 is the default.

Number	Function	Output
0	Basic	Returns the last or first year of the century. (Last if Common Era, first if Before Common Era.)
1	Index	Returns a number counting the number of centuries from the 1st century BCE. ie. 1st century BCE = 0, 1st century BCE = 1, 2nd century BCE = -1
2	Absolute	Returns the numeric part of the input only. Note that this will never return 0.
3	Logic	Returns a 1 (one) if the input is a recognised century.

If the input is not a recognised century, this template will return FALSE; unless function 3 is selected, in which case it will return 0 (zero).
