Examples of RationalNumber

de.lmu.ifi.dbs.elki.data.RationalNumber
RationalNumber represents rational numbers in arbitrary precision. Note that the best possible precision is the primary objective of this class. Since numerator and denominator of the RationalNumber are represented as BigIntegers, the required space can grow unlimited. Also arithmetic operations are considerably less efficient compared to the operations with doubles. @author Arthur Zimek
