Conditional Jump Using A Relational Operator; Other Program Statements - Casio fx-3650P User Manual

• Example: Use Heron's formula to perform a series of calculations to
determine the area of triangles for which the length of side A is fixed, and
the lengths of sides B and C are variable.
Program
?→A: Lbl 1: ?→B: ?→C: (A + B + C) ÷ 2→D^D × (D – A) × (D – B) ×
(D – C): Ans^Goto 1
kConditional Jump Using a Relational Operator
You can use relational operators so program execution compares two
values and then decides which processing should be performed based on
the relationship between the two values.
• Example: To create a program that calculates the total of a series of input
values, with calculation being terminated whenever zero is input
Program
0→B: Lbl 1: ?→A: A = 0 S Goto 2: B + A →B: Goto 1: Lbl 2: B
1
1 Assigns 0 to variable B.
2 Assigns the input value to variable A.
3 If A = 0 is true, Statement 1 (Goto 2) is executed. If false, execution
advances to Statement 2 without executing Statement 1.
u Relational Operator Notes
• The relational operators you can use in a program are: =, G, >, >.
• A relational operation that is true returns a value of 1, while a false
relational operation returns a value of 0. For example, executing 3 = 3
would return a result of 1, while 1 > 3 returns a result of 0.
