API Summary

CurrencyParser works in any Ruby class, it does not require Active Record or other ORM. Its default settings has it configured for the German currency format, without allowing negative values.

parser = CurrencyParser::Parser.new
=> #<CurrencyParser::Parser:0x007feca487fe68
 @allow_negative=false,
 @delimiter=".",
 @format=:de,
 @separator=",">

parser.to_us("1,23")
=> "1.23"

parser.to_us("-1,23")
=> "1.23"

The same can be achieved without any change to the default configuration via

CurrencyParser::Parser.to_us("1,23")
=> "1.23"

As of v0.1.2 only the :de format is supported and you can allow negative values as follows

parser = CurrencyParser::Parser.new(:de, :allow_negative => true)
=> #<CurrencyParser::Parser:0x007feca9f999d8
 @allow_negative=true,
 @delimiter=".",
 @format=:de,
 @separator=",">

parser.to_us("-1,23")
=> "-1.23"

Invalid formats will raise an InvalidFormatError exception.
