public class FloatControl

extends EmptyStringNullableControl

implements FilteredInputControl

This class represents a textbox control that accepts only valid floating-point numbers. This class does not support localization. It does not use @link NumberFormat class to parse and format @link BigDecimal objects because @link NumberFormat would convert @link BigDecimal objects into doubles. To customize parsing and formatting one could create a subclass of it and override @link #createBigDecimal(String) and @link #toString(BigDecimal) methods. To use the subclass in JSPs also another JSP Tag must be created to use this implementation and configure validation script.
