Specified by:

setUp in interface IEvaluator

Overrides:

setUp in class AbstractSymbolEvaluator

Parameters:

symbol - the symbol which should be set up

numericEval

public IExpr numericEval(ISymbol symbol)

Description copied from interface: ISymbolEvaluator

Numerical evaluation of a symbol

Specified by:

numericEval in interface ISymbolEvaluator

Overrides:

numericEval in class AbstractSymbolEvaluator

Parameters:

symbol - the symbol which should be evaluated

Returns:

the evaluated object or null, if evaluation isn't possible

evalReal

public double evalReal()

Description copied from interface: ISignedNumberConstant

Evaluate the symbol to a double number

Specified by:

evalReal in interface ISignedNumberConstant

Returns:
