--NOTES:
--    [ These comments are skipped by <noinclude> and not sent
--      in formatted Internet pages, only during edit. ]
--
--NOTE A1: This template handles a number+fraction, for display,
--     based on amount as negative/0/positive, using -1/0/1 as
--     suffix: #expr:( {{{2|6+3}}}*0>0) - ( {{{2|6+3}}}*0<0) so
--     positives are /frac1, zero as /frac0, negatives /frac-1
--     without using a nested if-statement to choose 1/0/-1.
--     During 2009-2010 templates were restricted to if-logic
--     nested within depth of only a 40-level limit.
--
--NOTE P2: The parameters, as fraction parts, expect input like
--     #titleparts splitting a number at "/" (slash), where
--        parameter 1 - is the original number (like 6+3/8)
--        parameter 2 - is left of slash (6+3)
--        parameter 3 - is after slash (8) as the denominator.
--
--NOTE S3: Parameters here should NOT have spaces or split on
--     separate lines: {{hands/numdisp/fracparts|0|6+3 |8}}
--     would put a space after 3, as "3 /8" in the displayed
--     fraction. The MediaWiki parser appends a newline ending
--     a parameter when "|" is on the next line (in 2010).

-- 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).

{{doc|content=
This subtemplate is called by {{tl|hands/numdisp}} <!-- and by {{tl|convert/and/frn1}} --> to process fractions according to whether the whole number part (i.e. the ''a'' in {{frac|''a''|''b''|''c''}}) is positive, negative or zero calling {{tl|hands/numdisp/frac1}}, {{tl|hands/numdisp/frac-1}} or {{tl|hands/numdisp/frac0}} respectively.
