* \brief A validator for validating floating point user input.
*
* This validator checks whether user input is a double in the pre-defined
* range.
*
* \if cpp
* Usage example:
* \code
* Wt::WLineEdit *lineEdit = new Wt::WLineEdit(this);
* Wt::WDoubleValidator *validator = new Wt::WDoubleValidator();
* lineEdit->setValidator(validator);
* lineEdit->setText("13.42");
* \endcode

* <h3>i18n</h3>
*
* The strings used in this class can be translated by overriding
* the default values for the following localization keys:
* Wt.WDoubleValidator.NotANumber: Must be a number
* Wt.WDoubleValidator.TooSmall: The number must be larger than {1}
* Wt.WDoubleValidator.BadRange: The number must be in the range {1} to {2}
* Wt.WDoubleValidator.TooLarge: The number must be smaller than {1}
