数值函数

Recall the following odd function below, which determines whether a numeric argument is odd or even returning 1 for odd numbers and 0 for even numbers

Scanning each character in the expression to separate and record operators, operational symbols and data types of operators, when expression being correct in syntax, recording interpreter executive order based on precedence of operator, a general expression interpreter is designed. The interpreter not only is used for numerical value and string computation, but also is easy to extend its functions, and when batch converting data, it could catch run error and continue to successive data.
