Custom Numeric Type Support link
Types that can be converted from a string, via a TypeConverter or assigning ConvertValue, get basic support from Numeric. If the type implements a TypeConverter that can convert to/from decimal, then Step and Min/Max are supported. If the type implements IFormattable, Format strings will be passed to it.
