Features
Read full description

The scientific notation means that you enter a number as a number multiplied by ten in effect. Scientists and engineers often work with very large or very small numbers, which are more easily expressed by exponential or scientific notation. A classic chemical example of a number written in a scientific record is Avogadro's number (6.022 x 1023). Scientists usually perform calculations using the speed of light (3.0 x 108 m / s). An example of a very small number is the electric charge of one electron (1,602 x 10-19 Coulombs).

Verdict

The call

The clearest difference is rating: Calculator # at 4.6 against Scientific Notation Calculator's 1.0. Calculator # also leads on ratings volume (36K vs 1). Scientific Notation Calculator's advantage is in-app purchases (none vs 6) and ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
