# 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.
