Remarks
This Enum contains a list of built-in data types that come with uCalc.
It can be used with functions that expect a data type. For instance, you can specify a data type other than the default Double for [topic: uCalc.Parse]. You can also set the default data type for a uCalc instance with [topic: uCalc.DefaultDataType]. Typically with such functions, you can use either a [topic: uCalc.DataType] object, a string containing the data type name, or a BuiltInType Enum member for functions that require a data type. A string is the least efficient, while a data type object is the most efficient. Internally an enum is first converted to a data type object.
To set up a data type though with [uCalc.DataTypeOf] you can pass a member from this Enum.
If you have a data type object, you can retrieve the Enum numeric value associated with that type using [topic: uCalc.DataType.Index]
Note: Not all of the listed data types are implemented in the current version.
