Template talk:Convert/nesting

This is the talk-subpage for: Template:Convert/nesting.

Purpose
11-March-2010: This page is used to discuss issues about the depth of nest-levels of the multi-nested subtemplates in Template:Convert. There are related talk-subpages:


 * Also see: Template_talk:Convert - for general discussion.
 * Also see: Template_talk:Convert/density - about density conversions.
 * Also see: Template_talk:Convert/updates - for requesting protected updates.

This talk-subpage is intended to discuss changes to improve the nesting, or improve the explanations, or to help determine the nest-level of a conversion. -Wikid77 (talk) 10:43, 10 March 2010 (UTC)

New rounding routine for less nesting
11-March-2010: There is a new, simplified rounding subtemplate, rndpad, which is intended to bypass the complex, scientific notation rounder, rnd, except for extremely large amounts. For amounts above 10 billion, or rounding above 10-thousand (where n < -5), the full Template:Rnd should be used. However, for most amounts, there is no need to prepare for scientific notation, so the rounding could be done much faster and simpler by rndpad, which can show 10-digit amounts, while also padding for trailing-zeroes in decimal results.

The planned update, to begin using rndpad, would require changing Convert/round to invoke "rndpad" rather than "rnd" (with the same parameters). However, those changes should be tested in sandbox versions of the subtemplates. -Wikid77 10:43, 10 March 2010 (UTC)

Notice of updating Rnd to bypass Rnd/a
11-April-2010: This is just an FYI that Template:Rnd has been updated (on 5 April 2010) to bypass the small subtemplate {Rnd/a} to reduce Convert nesting by 1 more level, against the template-nesting limit. This change affected nearly 307,000 pages, and dropped 307,000 wikilinks to {Rnd/a}, which then become almost unused. See counts in database report:
 * WP:Database reports/Templates with the most transclusions (for Rnd & Rnd/a)

The full talk-page topics are in Template_talk:Rnd:
 * Template_talk:Rnd
 * Template_talk:Rnd
 * Template_talk:Rnd

Those topics describe the issue, with examples. After update, then 305,700 articles were auto-reformatted to de-link {Rnd/a} (within 5 hours on a Sunday night). However, another 1,195 articles were "stuck" as still linking to the unused {Rnd/a}, but hundreds per day later de-linked it, after each article was edited by the pool of thousands of active editors. -Wikid77 18:03, 11 April 2010 (UTC)
