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.

The calculator spits out something that looks like this: 6E24. What in the world is that? Basically, when a scientific calculator has to deal with very large or very small numbers that it doesn't have enough room to display on its screen, it will use it's own form of scientific notation. In this example, 6E24 tells us that the answer is 6 followed by 24 zeros. In other words, the E24 in 6E24 tells us to move the decimal point in 6 twenty-four units to the right. By default, scientific calculators, like regular ones, display fractions as decimals. So if you enter a simple fraction, such as 1/2, the display reads 0.5. Some – but not all – scientific calculators offer a feature that allows you to display fractions without making the conversion. Using this feature, you can enter a complex fraction and simplify it right on your calculator. Calculators with this feature also allow you to enter a number composed of an integer and a fraction, such as 1 1/4. If your calculator doesn't have this feature, you can use a workaround to manipulate fractions. (Source: sciencing.com)
