Members,

Is there any function in COBOL which will retrieve square as well cube of any number and how to represent the notations in the calculations ?
For example:
8 square = 64
8 cube = 512

mfuser,

Exponentiation in cobol is denoted by ** operator. So square = n to power of 2 and cube is n to the power of 3. ( n = number)

check this

Code:

01 WS-INP-NUM              PIC S9(09) COMP VALUE 8.
01 WS-SQUARE               PIC S9(15) COMP-3.       
01 WS-CUBE                 PIC S9(15) COMP-3.       
                                                   
                                                   
PROCEDURE DIVISION.                                 
                                                   
     COMPUTE WS-SQUARE = WS-INP-NUM ** 2           
     DISPLAY 'THE SQUARE IS : ' WS-SQUARE           
                                                   
     COMPUTE WS-CUBE   = WS-INP-NUM ** 3           
     DISPLAY 'THE CUBE IS   : ' WS-CUBE             


Hope this helps...

Cheers
