Description
Will display either the value of or the symbol of a maths constant chosen by the user.
Parameters
{{constant | {{{1}}} | {{{2}}} | places= | round= | link=}}
|{{{1}}}
- Required. Defines which constant to display.
- Possible Values: e; pi; tau; root2; phi; plastic; i;
|{{{2}}}
- Suggested. Defines whether to display the value of the constant or the symbol.
- Possible Values: symbol; value; Default: value
|places=
- Suggested. Defines the number of decimal places to display. Ignored if displaying symbol.
- Possible Values: Any integer from 0 to 50; Default: 8
|round=
- Choose whether or not to round when picking number of decimal places.
- Possible Values: true; yes; y; Default: false
|link=
- Choose whether or not to turn the symbol into a wiki-link that leads to the constants' respective pages. Ignored if displaying value.
- Possible Values: true; yes; y; Default: false
