This abstract class is the base class of all discrepancy classes programmed with floating-point numbers with multi-precision.
For \(n\) large, computing the discrepancy suffers from subtractive cancellation and loses all precision if one uses double
numbers. Using multi-precision numbers allow us to compute the discrepancy for larger \(n\), but the computation is very slow.
