The approximated value (between 0 and 1) on the path which is closest to the specified value.
Note that the implementation of this method might be optimized for speed against precision,
see locate(Object) for a more precise (but more intensive) method.
The precise location (between 0 and 1) on the path which is closest to the specified value.
Note that the implementation of this method might be CPU intensive, see approximate(Object) for
a faster (but less precise) method.
