where,

• Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle SomeNumber} is any real number.

FIBONNACI() displays the Fibonacci series up to the number specified in argument.

Description

FIBONNACI(SomeNumber) or FIBONACCI(SomeNumber)

e.g. FIBONNACI(3) returns 0, 1, 1, 2 as a result.

FIBONACCI(6) returns 0, 1, 1, 2, 3, 5, 8 as a result.

• Fibonacci sequence is a series of numbers in which, after first two numbers each subsequent number is the sum of the previous two numbers.
• Fibonacci sequence is as follows -

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, .......

• Argument Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle SomeNumber} specifies the count of numbers for which the sequence is to be displayed.

e.g. if Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle SomeNumber} is '3', Calci displays Fibonacci series up to 3 numbers excluding '0'.

• If Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle SomeNumber} < zero(0), Calci displays #NULL error message.
• If Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle SomeNumber} is not an integer, Calci rounds it up to display the result.

• Both spellings supported - FIBONNACI(SomeNumber) or FIBONACCI(SomeNumber)
