uCalc comes with a list of predefined intrinsic data types, including several integer types, floating point types,
a complex number type, string types, collection (list) types, as well as other special types. The full list can
be found under BuiltInTypesEnum.
You may also define your own data types that operate at the same as uCalc's intrinsic types.
uCalc also lets the end-user define their own type.
