I am using the number to currency function because i live in the uk and  
the company want me to only show values of the pound of course.I have  
created all my application using ruby script/generate  
scaffold\_resource… I have come across with a problem… this code is  
in my applcation:

def number\_to\_currency(number, options = {})  
options = options.stringify\_keys  
precision, unit, separator, delimiter = options.delete(“precision”) {  
2  
}, options.delete(“unit”) { “£” }, options.delete(“separator”) { “.” },  
options.delete(“delimiter”) { “,” }  
separator = “” unless precision \> 0  
begin  
parts = number\_with\_precision(number, precision).split(’.’)  
unit + number\_with\_delimiter(parts[0], delimiter) + separator +  
parts[1].to\_s  
rescue  
number  
end  
end

it definately should work, but why doesnt the £ sign come as a question  
mark I have also tryed:

def number\_to\_currency\_gbp (number)  
number\_to\_currency(number, { :unit =\> “£”})  
end

This doesnt work either it is not picking up the &pound how can i solve  
this problem thanks

this works for me…

\<%= number\_to\_currency(12.65, :unit =\> “£”) %\>  
returns =\> £12.65

does that help?

crap, Google converted it for me. I meant this (take out the  
'_remove_’s):  
\<%= number\_to\_currency(12.65, :unit =\> “&_remove\_pound\_remove_;”)  
%\>
