BigDecimal extends the native String class to provide the to_d method.
When you require BigDecimal in your application, this method will be available on String objects.
Convert string to a BigDecimal and return it.
require 'bigdecimal' require 'bigdecimal/util' "0.5".to_d # => 0.5e0
# File bigdecimal/lib/bigdecimal/util.rb, line 60
def to_d
BigDecimal(self)
end
