−14,000.

Template documentation[view] [edit] [history] [purge]

The Template:Hands/numdisp processes a number, for display, by checking to display a fraction part (at "/"), else it just uses parser-function {{formatnum:{{{1|6000}}}}} to add commas, such as to show "6,000".

Usage:  {{hands/numdisp|6+3/8}} → 6 38
{{hands/numdisp|-4-1/2}} → −412
{{hands/numdisp|23500}} → 23,500
{{hands/numdisp|2300+643/1250}} → 2,300 6431250
{{hands/numdisp|&minus;7.0}} → −7.
{{hands/numdisp|14+6/ }} → Expression error: Unexpected < operator

Implementation

The check, for fraction parts, uses parser-function {{#titleparts:xx/xx|1|2}} to split a number at "/" (if any, as in: 6+3/8) and then checks if part 2 (the denominator, after the slash) contains a number, to trigger use of {{hands/numdisp/frac}}). Hence, the template uses:

#if: {{#titleparts:{{{1|6+3/8}}}|1|2}}

That if-expression will be true if a denominator exists (such as "8" in 6+3/8).
