Class Attribute Details

.assume_from_symbol ⇒ Object

Returns the value of attribute assume_from_symbol.

end

.enforce_currency_delimiters ⇒ Object

Monetize uses the delimiters set in the currency to separate integers from decimals, and to ignore thousands separators. In some corner cases, though, it will try to determine the correct separator by itself. Set this to true to enforce the delimiters set in the currency all the time.
