HP Prime and Casio fx-CG 50: Leap Year
Test
Introduction
The presented
program tests whether a year is a leap year.
A leap year has 366 days instead of 365, with the extra day given to
February (February 29). The criteria for
a leap year are:
* Leap years
are year numbers evenly divisible by 4.
Example: 1992, 2016
*
Exception: years that are divisible by
100 but not divisible by 400.
Example: 2000 is a leap year, but
1900 and 2100 aren’t.
HP Prime Program ISLEAPYEAR
EXPORT ISLEAPYEAR(y)
BEGIN
IF FP(y/4) ≠ 0 OR
(FP(y/100) == 0 AND FP(y/400) ≠ 0)
THEN
RETURN 0;
ELSE
RETURN 1;
END;
END;
Casio fx-CG 50 ISLEAPYR
“YEAR”? → Y
If Frac(Y ÷ 4) ≠ 0
Or (Frac(Y ÷ 100) = 0 And Frac(Y ÷ 400) ≠ 0)
Then
“No” ◢
Else
“YES” ◢
