DSP.filter.Rational
cc.redberry.core.number.Rational
Representation of a rational number without any overflow. This class is a wrapper of {@link BigInteger}.

This class implements mathematical operations declared in {@link cc.redberry.core.number.Number} as operations with in the followingway. If argument is {@link Numeric}, the result will be {@code Numeric} too.For example, 2 / 3 +1.0 will give 1.666666 and so on. If argument is {@code Rational}number, the result will be {@code Rational} too. @author Stanislav Poslavsky @see Number @see Numeric @see BigFraction
