Library "Fibonacci" General Fibonacci functions. Get fib numbers, ratios, etc.
fib_precise(f, precision) Get the precise Fibonacci ratio, to the specified number of decimal places Parameters: f: Fibonacci ratio (string, in form #.###) precision: Number of decimal places (optional int, dft = 16, max = 32) Returns: Precise Fibonacci ratio (float)
fib_n(n) Calculate the Nth number in the Fibonacci sequence Parameters: n: Index/number in sequence (int) Returns: Fibonacci number (int)

v4 Hard-coded precise fibs for efficiency (rather than deriving them)
Added: fib_derived(f, precision) Get the precise Fibonacci ratio, to the specified number of decimal places Parameters: f: Fibonacci ratio (string, in form #.###) precision: Number of decimal places (optional int, dft = 16, max = 32) Returns: Precise Fibonacci ratio (float) * Deprecated (use fib_precise() instead), but keeping it here for science / experimenting with derivations
