RationalFunction - crowlogic/arb4j GitHub Wiki

A rational function is defined as the ratio of two Polynomials. More specifically, a rational function R(x) can be expressed as:

R(x) = P(x) / Q(x),

where P(x) and Q(x) are both polynomials, and Q(x) ≠ 0 (i.e., the denominator cannot be zero). The domain of a rational function is the set of all real numbers for which the denominator Q(x) is nonzero.
