Description

• This function shows the factorial value up to the mentioned value.
• In 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 FACTUNTIL (Number,NumberTill)} , 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 Number} is the value to start and $NumberTill$ is the maximum limit value.
• Factorial means the result of multiplying a sequence of descending natural numbers down to 1.
• So the factorial 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 n!} is defined for a positive integer n as:

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 n!=n*(n-1)*...2*1} .

• For example FACTUNTIL(9,4) calculates the value of 9*8*7*6*5.

Examples

1. FACTUNTIL(10,7) = 720
2. FACTUNTIL(54,45) = 1929772710028800
3. FACTUNTIL(9,6.2) = 504
