Introduction

The  Boolean operation in  Boolean  function can be used to converts the argument/parameter into the boolean format. Some points regarding the number function are:

If the argument is a positive or a negative number then the Boolean value is true.
If the argument is a zero (0) or NaN then the Boolean value is false.
If the argument is a  non-empty string then it is converted to boolean value true.
If the argument is a empty string then the boolean value is false for it.
If the argument is a  non-empty node-sets then it is converted to boolean value true.
If the argument is a empty node-sets then the boolean value is false for it.
