MTech–Module 2: Lecture 04

Calculator Programming

1. Input 2 numbers and compare them:


CASIO fx-3650P
? → A : ? → B: A > B
CASIO fx-50FH
? → A : ? → B: A > B

Input (A ?) Input (B ?) Display


1. 1 2
2. 5 5
3. −3
3

4. −3.45 22
7

Conclusion: If A > B , then the Display will be ____


If A = B , then the Display will be ____
If A < B , then the Display will be ____

2. We can scale the displays to different values


example: (a) modify the codes to
? → A : ? → B: 2 (A > B)
then the values will be
A> B A≤ B
Display
(b) modify the codes to
? → A : ? → B: 5 (A > B) + 3
then the values will be
A> B A≤ B
Display
(c) modify the codes to
? → A : ? → B: −3 (A > B) + 1
then the values will be
A> B A≤ B
Display

MTech–Module 2: Lecture 04

Exercise:
(a) modify the codes such that the values will be
A> B A≤ B
Display 3 2
(b) modify the codes such that the values will be
A> B A≤ B
Display 5 10
(c) Conclusion:
If we want the values to be
A> B A≤ B
Display a b
then we have to modify our codes to be
? → A : ? → B: m (A > B) + c
where m = __________ and c = __________

3. Modify the program to use other comparison operators “=”, “ ≠ ”, “ ≥ ” etc.
