My high school assignment

Posted by Matt Gerrans on October 26, 2001 at 2:03 AM

Yee gads! Soon as I posted the note, I noticed that my little fibonacci calculator was not calculating fibonacci, but instead gerronacci numbers (which is an increasing sequence of numbers that future astrologers and numerologists will find to be uncanny predictors of personality traits, foibles and tendencies, based on the day of month and hour of birth combined with the biorythm of the victi-uh, client). This is probably punishment for my slight of ja(va)rule (sorry, but my sensibilities were somewhat inflamed by his racist comment about Chin Loong).

Anyway, I think the following will give a closer approximation of actual Fibonacci numbers (or else the Fibo-nazis out there will be quick to let me know otherwise, I'm sure).

public static long getNthFibonacci( int n )
if( n < 1 || n > END )
throw new IndexOutOfBoundsException();
else if( n == 1 )
return 0;

long fibonacci = 1, current = 1, prev = 0;

for( long i = 2; i < n; i++ )
fibonacci = prev + current;
prev = current;
current = fibonacci;

return fibonacci;
