<!--endif {#titleparts..} -- --NOTES: --    [ These comments are skipped by and not sent --      in formatted Internet pages, only during edit. ] -- --NOTE A1: This template processes a number, for display, by --    checking to display a fraction part ("/"), else it --     will check for negative to display a unicode &minus --    and 0 such --    as "-6000" with a full minus sign rather than hyphen. --    In 99% of Wikipedia usage, there are no fractions. -- --NOTE D2: The check, for fraction parts, uses parser-function --    #titleparts to split the number at "/" (if any) and --    then checks part 2 (the denominator, after the slash) --    to trigger use of. Hence, --        #if: --    will be true if a denominator exists (such as "8"). -- --NOTE N3: This template uses minimal expansion depth of the --    if-else logic by checking for "/" before invoking the --    nested subtemplate. The --    check for a negative number increases the nesting depth --    by 1 level to apply abs({1}) in a nested {#expr:} parser --    function, to use the absolute value of the amount {1}. -- --NOTE Z4: Any end-zeroes on a decimal are preserved by not --    using positive amounts in an expression, and for rare --    negative amounts, the &minus with inverse - {1} is padded --    by {padright:} with end-zeroes "0" to {strlen_short} but --    uses #ifexpr:{1}0={1} and floor({1})={1} to put ".". --    So, {strlen_short} keeps minimal expansion depth of +2. -- -- WARNING: *** DO NOT DELETE COMMENTS FROM THIS TEMPLATE *** --     Unless these comments are readily available, people --     might tinker with the coding (or rename templates), --     in hopes to clarify operation because these comments --     were not nearby to explain the issues. Having these --     comments only on a doc-page increases the danger of --      explanations no longer matching the current coding. --     UPDATE these comments to match changes to the template. --     UPDATE the HISTORY during major changes (not typos). -- -- --HISTORY: --03Apr09 Created by User:Jimp on English Wikipedia. --19Nov10 Invokes subtemplate only if has denominator (at "/"). --19Nov10 Put NOTES comments to explain template coding. --19Nov10 Put HISTORY comments to log major changes. --19Nov10 Put all parameters on 1 line to avoid newline "2^ /3" --20Nov10 Linked {Documentation} to hold any interwiki links. --12Feb11 Shows Unicode &minus ("−") for negative numbers. --17Feb11 Used {padright:} to re-add end-zeroes on negatives. --17Feb11 Used #ifexpr:{1}0={1} and floor({1})={1}, to put "." --30Nov13 Fixed to allow prefix "&minus;" as extra 6 long. --07Jan14 Fixed to pass negative sum without padding "0". -- ** Add interwiki links to /doc subpage to avoid changes here ** -- -->
