All Implemented Interfaces:

PostfixMathCommandI, RealUnaryFunction, java.io.Serializable
```
public class LogBase2
extends UnaryFunction
implements RealUnaryFunction
```
Log base 2. Other bases can be specified in constructor. Behaviour for negative real values are specified by the strict argument.
