Frequently asked questions
Does the calculator follow BODMAS?
Yes. Brackets are evaluated first, then powers, then division and multiplication, then addition and subtraction. Powers are right-associative, so 2^3^2 = 2^9 = 512.
How do I calculate sin, cos and tan in degrees?
Select DEG (the default) and type sin(30), which gives 0.5. Choose RAD for radians.
Which functions are supported?
sin, cos, tan and their inverses, sinh, cosh, tanh, sqrt, cbrt, ln, log (base 10), log(x, base), exp, abs, floor, ceil, round, factorial (n!), nCr, nPr, mod and the constants π and e.
