Hi,

I wonder if there is something like $subj so that I don’t reinvent the  
wheel. What I need is something like:

money\_to\_val(‘$12.56’) =\> 12.56  
money\_to\_val(‘$ 12.56’) =\> 12.56  
money\_to\_val(‘$ 12,56’) =\> 12.56  
money\_to\_val(‘US$ 12,56’) =\> 12.56  
money\_to\_val(‘12.56$’) =\> 12.56  
money\_to\_val(‘USD 12.56’) =\> 12.56

maybe even

money\_to\_val(‘12 dollars, 56 cents’) =\> 12.56

Probably what I need to cover 95% of the cases is to remove all the  
non-digits except a delimiter (, or .) I guess. Or not?

Thanks,  
Peter

Attention to locales! At least these variants for 1234567.89 exist in  
different countries:  
1 234 567,89  
1.234.567,89  
1,234,567.89  
1 234 567.89  
1’234’567.89  
1,234,567·89
