SYNOPSIS

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

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.
