NAME

Math::Fibonacci - Fibonacci numbers.

VERSION

    $Revision: 1.5 $

SYNOPSIS

    use Math::Fibonacci qw(term series decompose);

    my $term = term ( 42 );
    my @series = series ( 42 );
    my @sum = decompose ( 65535 );

DESCRIPTION

This module provides a few functions related to Fibonacci numbers.

EXPORTS ON REQUEST

term(), series() decompose(), isfibonacci()

FUNCTIONS

term($n): Returns the $n-th term of the Fibonacci sequence. The term is computed using the fast algorithm: F(n) ~ g^n/sqrt(5), where g is the golden ratio and ~ means ``take the nearest integer''.
series($n): Computes and returns the first $n Fibonacci numbers.
decompose($int): Decomposes $int into the sum of Fibonacci numbers. Returns the list of Fibonacci numbers.
isfibonacci($int): Returns the sequence number of $int if it is a Fibonacci number or a non-true value if it is not.
