| We can build a cent function:
| |
| | |
| <nowiki>* {{#expr: ln (9/8) / ln 2 * 1200}}
| |
| * {{#expr: ln (3/2) / ln 2 * 1200}}
| |
| * {{#expr: ln (5/4) / ln 2 * 1200}}</nowiki>
| |
| | |
| * {{#expr: ln (9/8) / ln 2 * 1200}}
| |
| * {{#expr: ln (3/2) / ln 2 * 1200}}
| |
| * {{#expr: ln (5/4) / ln 2 * 1200}}
| |

| but for formatting rounded results, it would be good to use [https://www.mediawiki.org/wiki/Extension:NumberFormat Extension:NumberFormat - MediaWiki]
| |
| | |
| ... which is currently not available (it's displaying just the code I typed):
| |
| | |
| {{#number_format:12 345 678,055555|_|.||,}} | |
| | |
| '''The Problem''' that can be solved by <code><nowiki>{{#number_format: [...]</nowiki></code> is that
| |
| <code><nowiki> {{#expr: (ln (3/2) / ln 2 * 1200) round 5}}</nowiki></code> gives us <tt>{{#expr: (ln (3/2) / ln 2 * 1200) round 5}}</tt> instead of <tt>701.95500</tt> if 5 decimals are requested, as indicated by the <tt>5</tt> after <tt>round</tt>.
