Have you ever been tired of explaining to someone how to interpret the moving figures on a calculator? Here's how to avoid those headaches.

Calculator

Most scientific and graphing calculators can only display possibly up to 10 decimal places of accuracy. While this is enough in most instances of everyday use, it can be fairly limiting for applications where higher standards of accuracy are necessary. Hence the existence of big number calculators such as the one above, that can provide far higher levels of accuracy. Big numbers are more likely to be used in fields such as cosmology, astronomy, mathematics, cryptography, and statistical mechanics. 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.

Significant figures are all numbers that add to the meaning of the overall value of the number. To prevent repeating figures that aren't significant, numbers are often rounded. One must be careful not to lose precision when rounding. Many times the goal of rounding numbers is just to simplify them. Use the rounding calculator to assist with such problems.
