dojo.number.format with 0 leading zeros shows one leading zero

[bmilcke]

dojo.number.format(0.123, { pattern: "#.##"}); returns "0.12" instead of ".12".

sorry, forgot the component. Cannot change this now, obviously.

@bmilcke, try pattern: "0.##" I know this pattern stuff seems ambiguous (tried to implement from CLDR which copies from Java) but I think you're really supposed to have at least one '0' in the pattern? (General component is fine, btw)

[bmilcke]

Well at ​http://unicode.org/reports/tr35/#Number_Format_Patterns it is stated:

For consistency in the CLDR data, the following conventions should be observed so as to have a canonical representation:

• All formats should have one 0 before the decimal point (for example, avoid #,###.##)

So, it is correct that you should avoid it. However I find the result unexpected.

• All number patterns should be minimal: there should be no leading # marks except to specify the position of the grouping separators (for example, avoid ##,##0.###).

Well, at least I don't really understand this then, or there is a bug in Dojo?

dojo.number.format(123, {pattern:"0.##"}); -> 3

dojo.number.format(123, {pattern:"#0.##"}); -> 123

So, you need a leading #.

You're right, the latter part is probably a bug, but one with a workaround. I really hate that spec. It's unnecessarily complex.
