Class MathClient

java.lang.Object
  infix2postfix.Infix2PostfixClient
      infix2postfix.MathClient

public class MathClient

extends Infix2PostfixClient

This class represents client interface for Infix to postfix conversion and postfix evaluation for mathematical expressions.
This math client supports operators like,

 1. +
 2. -
 3. unary -
 4. *
 5. /
 6. max (function operator)
 

This math client supports following basic data types to provide more control over results and operand value ranges,

 1. int
 2. long
 3. float
 4. double
 

In addition, this client supports various radix systems defined in range- Character.MIN_RADIX and Character.MAX_RADIX.
