Numeric Entries
===============

All numeric entries in Dune 3D support basic two-operand math as well as some other goodies.

They look like these:

Both point and comma are recognized as a decimal separator regardless of locale settings. By default all numbers are treated as millimeters. Suffixing a number with an ``i`` or ``in`` will treat it as inches. Use ``mi`` or ``mil`` to convert from thous.

Additionally, two-operand infix math is supported, so you can do operations such as:

- Addition: ``1+2``
- Subtraction: ``1-2``
- Multiplication: ``3*2``
- Division: ``3/2``
- Average :math:`\frac{ a+b }{2}`: ``3|2``
- Adding mm and inch: ``1in+2mm``
