Template:Valid/doc

This is a documentation subpage for Template:Valid (see that page for the template itself).
It contains usage information, categories and other content that is not part of the original template page.

Purpose

Determines whether something is valid in a certain context. Currently only implemented for determining if a number is within the precision that wikipedia expressions can handle.

Returns

true if the argument is valid, false if it is not.

Examples

{{valid|number=A}} = false (not a number)

{{valid|number=1234}} = true

{{valid|number=+1234}} = true

{{valid|number=-1234}} = true

{{valid|number=(1234)}} = false (one pair of parenthesis is allowed)

{{valid|number=--1234}} = false (incorrect sign use)

{{valid|number=1234567890}} = true

{{valid|number=12345678901234567890}} = false (too large)

{{valid|number=1.234567890}} = true

{{valid|number=1.2345678901234567890}} = false (too many decimals)
