The datatype Float represents a 32-bit floating-point value, which is used for attributes that contain decimal numbers. It can be positive or negative, with thousand separators, and can have an optional exponent. For example, [[Psi beam:=4,297.31 e7]]
It allows for giving units after the number as well. Though Type:Float does not understand units (i.e. it performs no automatic conversion), a unit can be used to distinguish attribute values with different units. For example, [[Psi beam:=42 mindmelds]].
