Maths lessons
Show how quickly factorials grow, with the exact value.

Let visitors type a whole number and see its factorial live, exact to the last digit, with the digit count, the zeros at the end and a scientific form.
These are the actual published outputs of the widget. Type a whole number into any of them; the factorial updates as you type.
Content sets the largest n allowed (up to 5000), whether every digit is listed, whether digits are grouped, and every label, including the hint and the starting number. The Style tab covers the field, the result box, the every digit box, labels and messages, and the Copy and Clear buttons.
Factorials grow so fast that most calculators switch to a rounded estimate after 20 or so. Maths lessons, probability pages and puzzle sites often need the real number. Factorial calculator sits on your own page: visitors type n and see n! exact to the last digit, how many digits it has, how many zeros it ends with and a short scientific form, all updated as they type. Nothing is sent anywhere.
