All the functions you'd expect

Sine, cosine and tangent, with inverse and hyperbolic versions. Natural and base 10 logs, powers, square roots, factorials, reciprocals, pi, e and a random number key.

Degrees or radians

Switch angle mode with one key. The display shows the whole expression and a live result, so you can catch a mistake before pressing equals.

Fix it without starting over

Delete the last thing you typed, or go back to a previous calculation in your history and carry on from there.
