  just that. 
 
                
             Irrational Numbers : If the decimal representation 
            of a number is non-terminating, non-reccuring type, then the number 
            is an irrational number or a number which cannot be expressed as a 
            ratio of two integers (p/q type), is called an irrational type. 
            
 For example, 0.10100100010001.....,  21.0120340560......,  the numbers p
 , e or all surds like  Ö
