Description

The org.apache.wicket.util.lang.Numbers class defines the method :
public static Number getMinValue(Class<? extends Number> numberType)

This method return the MatchingNumberTypeClass.MIN_VALUE.
But for Double.MIN_VALUE and Float.MIN_VALUE return the smallest positive number, not the smallest negative number like for the other number classes.

One side effect is that by default you can't enter a negative value, or a 0 in a NumberTextField<Double> or NumberTextField<Float>.
