Class DefaultNamespace

java.lang.Object
  com.bc.jexp.impl.NamespaceImpl
      com.bc.jexp.impl.DefaultNamespace

All Implemented Interfaces:

Namespace, WritableNamespace

public final class DefaultNamespace
extends NamespaceImpl

A default namespace which includes the constants PI, E and NaN as well as most of the functions from Java Math, e.g. sin(x), cos(x), tan(x), asin(x), acos(x), atan(x), atan2(x,y), log(x), exp(x), pow(x,y), sqrt(x,y), abs(x), min(x,y), max(x,y), floor(x), rad(x) (Math.toRadians(double)), deg(x,y) (Math.toDegrees(double)). inf(x,y) (Double.isInfinite(double)), nan(x,y) (Double.isNaN(double)).

The following functions are not taken from Java Java Math: log10(x), exp10(x), sign(x).

It also provides the fuzzy comparision functions feq(x, y), fneq(x).
