Fixed Point

From Free Pascal wiki

Free Pascal doesn't provide built-in language support for Fixed-point type. However there are a number of fixed point maths libraries available.

Due to the potential optimization of a certain operations (i.e. division or square root) the code might contain CPU specific inline assembly restricting the use of the library.
