Hello,

Today I noticed that the number\_to\_currency helper didn’t work anymore  
(it just returned the numeric value, without any currency).  
I tracked down the error and saw that editing line 89  
( number\_to\_currency method) as follows solved the problem :

Old piece of code :

begin  
format.gsub(/%n/, number\_with\_precision(number,  
:precision =\> precision,  
:delimiter =\> delimiter,  
:separator =\> separator)  
).gsub(/%u/, unit)  
rescue  
number  
end

New one :

begin  
format.gsub(/%n/, number\_with\_precision(number,  
:precision =\> precision,  
:delimiter =\> delimiter,  
:separator =\> separator).to\_s  
).gsub(/%u/, unit)  
rescue  
number  
end

Is it an issue with Rails ?

Thanks
