A NumericEnum expression that indicates whether integer or floating point
numbers are allowed.
The Numeric property has effect only if the editor contains
an edit box. Use the Numeric property to add intelligent input filtering for
integer, or floating points numbers. Use the exSpinStep
option to specify the proposed change when user clicks a spin control, if the
cell's editor is of SpinType type. Use the exEditDecimaSymbol
option to specify the symbol being used by decimal value while editing a
floating point number.
