--NOTES:
 
--    [ These comments are skipped by <noinclude> 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 {{formatnum:{{#expr:abs( {{{1|-6000}}} )}}}} 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 {{Convert/numdisp/fracparts}}. Hence,
 
--        #if: {{#titleparts:{{{1|6+3/8}}}|1|2}}
 
--    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 {{Convert/numdisp/fracparts}}. 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 "."
