I\'m using the WPF Extended Toolkit ( http://wpftoolkit.codeplex.com/ ).
It has a nice NumericUpDown control that I\'d like to use, but internally it uses doubles -
You should get the latest source code for the Extended WPF Toolkit. The updated NumericUpDown control allows you to specify what data type to use in the editor. The following code specifies to use an Int32 as the data type instead of the default double. As you can see this is done by setting the ValueType property on the NumericUpDown control.
