To use the calculator, simply type in the correct numbers in decimal format and click on any button below.


The majority of existing calculators are only able to display calculations with up to 10 decimal places of accuracy. Although this is sufficient in the majority of cases, it can be an issue if an application requires a higher degree of accuracy. As such, there is a requirement for big number calculators that can perform calculations to a higher accuracy level. Big numbers are frequently used in fields such as statistical mechanics, cryptography, cosmology, mathematics, and astronomy.

A big integer number is one that contains a larger number of digits than everyday numbers. For example, the speed of light, 299792458 m/s is a large number; however, it can be managed by standard calculators. In the fields of mathematics, cryptography, and quantum computing, numbers of an entirely different scale are employed. For example, the so-called googol, which incorporates 100 zeros and is expressed as 10100. The googol is frequently employed to express large quantities, even though it can be quantified.
