Detailed Description template<class Type> class EkRational< Type > The EkRational class provides a templated implementation of the rational number. A rational number is a fraction, p/q, where p and q are integers, with p being the Numerator and q the Denominator. This class can be constructed in several ways. First, using the constructor that takes two intergers the numerator and denominator. Second, using the default constructor and later supplying the numerator and denominator through class methods. Lastly, using the default constructor and supplying a floating point number to the rationalize() method that inturn calculates the integer numerator and denominator to the given precision (default is 1E-10). Smart pointers to the long and unsigned long versions of the EkRational class are pre-defined in the header file.
