Rational numbers, with numerator and denominator of some Integral type.
 Instances  



Arbitraryprecision rational numbers, represented as a ratio of
two Integer values. A rational number may be constructed using
the % operator.



Forms the ratio of two integral numbers.



Extract the numerator of the ratio in reduced form:
the numerator and denominator have no common factor and the denominator
is positive.



Extract the denominator of the ratio in reduced form:
the numerator and denominator have no common factor and the denominator
is positive.



approxRational, applied to two real fractional numbers x and epsilon,
returns the simplest rational number within epsilon of x.
A rational number y is said to be simpler than another y' if
Any real interval contains a unique simplest rational;
in particular, note that 0/1 is the simplest rational of all.
