QVariant

QVariant is analog to Quantity except that the dimensions are stored in a private field instead of a type parameter. This makes QVariant "dimensionnaly variant", so that a variable of type QVariant can hold quantities of variable dimensions. Yet, only operations that are dimensionnaly consistent can be performed on QVariant variables.

Warning: Contrary to Quantity, where all dimensional operations are done at compile-time, the dimensions of QVariant ate computed at runtime for each operation. This has a significant performance cost. Only use QVariant in situation where using Quantity is not possible, that is when the dimensions of the quantities are only known at runtime.
