DESCRIPTION
This module provides a few functions related to Fibonacci numbers.
EXPORTS ON REQUEST
term(), series() decompose(), isfibonacci()
FUNCTIONS
term($n)

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.
