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 com-
	   puted 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.
