This is a documentation subpage for Template:Convert/numdisp (see that page for the template itself). It contains usage information, categories, and other content that are not part of the original template page. |
Template:Convert/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: {{convert/numdisp|6+3/8}} → 63⁄8
-
- {{convert/numdisp|-4-1/2}} → −41⁄2
- {{convert/numdisp|23500}} → 23,500
- {{convert/numdisp|2300+643/1250}} → 2300643⁄1250
- {{convert/numdisp|14+6/ }} → Expression error: Unexpected < operator
-
Implementation [edit]
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 {{Convert/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).
