High Number Calculator

Easily calculate the digit sum in any number from 1-29.


Instead of calculating a factorial one digit at a time, use this calculator to calculate the factorial n! of a number n. Enter an integer, up to 4 digits long. You will get the long integer answer and also the scientific notation for large factorials. You may want to copy the long integer answer result and paste it into another document to view it.

A variation on the above method is to break the calculation into two parts, and use the memory functions of the calculator to store the result of the first part. The calculator memory is particularly useful when you want to calculate the values of several expressions that have a common part. This common part need be entered only once and its value reused several times subsequently. For example, rewriting the formula for the volume of wood contained in a log as (Source: www.open.edu)


I greatly appreciate the accuracy and flexibility of this calculator. It's very nice that I can use variables and nest functions, and the functions never seem to completely "zero out" due to a failure of precision like most calculators that are available for calculating hyperbolic trig functions. Especially since I am working with special relativity, where almost every single "daily life"-scale velocity is unbelievably small compared to the speed of light, so I am usually working with fractions on the order of a few billionths or smaller.

In some cases, the numbers worked with are so large that special notations such as Knuth's up-arrow notation, the Conway chained arrow notation, and Steinhaus-Moser notation were conceived. Nevertheless, there are certainly scientific uses for big number calculators today, and even if a person may not have any need to use one, it can certainly be entertaining to satiate one's curiosity of what 10,000 factorial looks like on a screen.
