Hello,

Using a locale I can format the same number for displaying it:

database: 1900.58  
en layout: 1,900.58  
cat layout: 1.900,58

this is ok …

but how I can do the reverse of it, when the user submits via form a  
number in it’s locale format ?

for example if the user enters in cat locale: 1900,58 the resulted  
number is 1900.00

currently I’m evaluating every field number and replacing commas by  
dots, but it’s a pain to format/adjust everyplace there is a number  
coming from a form.

I thought Rails I18n should handle this in a transparent manner … or  
sure I’m missing the point here and maybe there’s a function to do it  
…

thanks!
