Methods

EvaluateBinary(String, Double, Double)

Evaluates a binary operation.

public virtual double EvaluateBinary(string op, double a, double b);  

Parameters

op String: The operator.

a Double: Left value.

b Double: Right value.

Returns

Double: The result.

EvaluateUnary(String, Double)

Evaluates an unary operation.

public virtual double EvaluateUnary(string op, double a);  

Parameters

op String: The operator.

a Double: The value.

Returns

Double: The result.

GetBinaryPrecedence(String)

Returns the precedence of a binary operator. Unary operators have Precedence.Prefix precedence.

public virtual Precedence GetBinaryPrecedence(string operatorName);  

Parameters

operatorName String: The operator.

Returns

Precedence: A Precedence value.

IsBinary(String)

Tells whether an operator is binary.

public virtual bool IsBinary(string operatorName);  

Parameters

operatorName String: The operator.

Returns

Boolean: True if the operator is binary, false if it does not exist or it is unary.

IsUnary(String)

Tells whether an operator is unary.

public virtual bool IsUnary(string operatorName);  

Parameters

operatorName String: The operator.

Returns

Boolean: True if the operator is unary, false if it does not exist or it is binary.
