lispdoc - results for rational

(rational x)	Function: RATIONAL produces a rational number for any real numeric argument. This is more efficient than RATIONALIZE, but it assumes that floating-point is completely accurate, giving a result that isn't as pretty.

(rationalize x)	Function: Converts any REAL to a RATIONAL. Floats are converted to a simple rational representation exploiting the assumption that floats are only accurate to their precision. RATIONALIZE (and also RATIONAL) preserve the invariant: (= x (float (rationalize x) x))
