I18nTransformer patch
Hi folks,
here is a patch for I18nTransformer:
1) new tag int-currency introduced:
In merchandise calculations often
the calculations are done not with double
($1,23+$4,56) but with integers:
(cent 123+cent 456)
Soo give the value 579 will result
in 5.79 for US locale but 579 for spanish locale
because there is no sub currency in Spain.
2) the <i18n:number> tag did not preserve
trailing and leading zeros and did only show
three decimal places.
Soo <i18n:number>0.12345</i18n:number>
was transformed to 0.123
and <i18n:number>0.10000</i18n:number>
was transformed to 0.1
This is now fixed.
Could a commiter commit please?
Regards,
Michael
