com.singularsys.jep.reals.RealComponents

public class RealComponents
extends ComponentSet

A set of components for real (non-complex) evaluation. Evaluating sqrt(-1) will return NaN rather than a complex number. Function asin(2), acos(2), acosh(0.5), atanh(2), ln(-1), log(-1), lg(-1) also returns NaN. Furthermore, the constant i is not defined. This set of components does not use the RealEvaluator so it is still possible to mix doubles and strings.
