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[edit source]
Determines whether something is valid in a certain context. Currently only implemented for determining if a number is within the precision that expressions can handle.
Returns[edit source]
true if the argument is valid, false if it is not.
Examples[edit source]
{{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)
