 | Welcome to the TTSCpedia (beta)! This wiki is the successor to the FANDOM/Wikia version! You may create an account on the new wiki during the Public Beta stage and begin editing. Please see the to-do list here. Any content from the FANDOM/Wikia wiki will not be transferred automatically, such as pages, and accounts. That must be done manually by the end user, being you. |
 | Limited Feature Set Many TTSCpedia features are currently semi-broken due to regressions introduced with the MediaWiki upgrade. We hope to be fully operational again soon. The MonoBook skin has temporarily been set as the default skin due to Cali not being fully ported to the new version of MediaWiki. |

{{documentation subpage}}
This template rounds down a numeric value to a limited number of decimal places.
==Usage==
* <tt><nowiki>{{</nowiki>{{BASEPAGENAME}}<nowiki>|</nowiki></tt>''value''<tt><nowiki>}}</nowiki></tt>
* <tt><nowiki>{{</nowiki>{{BASEPAGENAME}}<nowiki>|</nowiki></tt>''value''<tt><nowiki>|</nowiki></tt>''decimals''<tt><nowiki>}}</nowiki></tt>
* Both parameters can be any valid numeric expression; however, ''decimals'' should be an integer.
* The ''decimals'' parameter defaults to 0.
* ''decimals'' can be negative to round down to a multiple of a power of ten.
* NAN may be returned if very large values are used.
