Template:Factorial/doc
From Wikipedia, the free encyclopedia
This template finds the factorial of a number. To use it, enter:
{{factorial|input}}
The input must be a positive integer smaller than 100 (better than most calculators, which go up to only 69). This template works by repeating conditional multiplications. Examples:
- {{factorial|2}} gives 2
- {{factorial|3}} gives 6
- {{factorial|5}} gives 120
- {{factorial|10}} gives 3628800
- {{factorial|80}} gives 3.719933267899E+41
- {{factorial|0.5}} gives 1 (invalid input)
- {{factorial|-1}} gives (invalid input)
