my suggestion would be to implement a method called power: in the

category Number



power: aNumber



     | result |

     aNumber timesRepeat: [result := result * self].

     ^result.





Of Course in the case of power, there is already a method implemented

called 'raisedTo:'

Hi !



If you want ABSOLUTELY a #power: or a #** method you should alias #raisedTo:



Number>>power: aNumber

    ^ (self raisedTo:aNumber)



The #raisedTo: method is more elaborated than a mere loop cause you

can reduce the complexity of a power calculus with logarithms. You

should really look at the #raisedTo: method...

Others have answered the question.  Just so you know, though, Ted Kaehler's

method finder is excellent for finding these answers.  If you start up

Squeak, open a method finder (with the "open" menu), and type in:



	 2 . 3 . 8



Then you will find the existing method for this operation.  This is

a fantastic tool for all the little basic questions that people have

when they are learning a new language.
