Scientific calculation
Operator precedence, parentheses, right-associative powers and defined implicit multiplication are supported. DEG uses degrees; RAD uses radians.
Trigonometric, inverse and hyperbolic functions, logarithms, roots, factorial, nCr and nPr are supported. Ans is the last successful result; memory and history exist only for this page session.
10% always means 10 / 100. There is no contextual percent behavior. The calculator uses IEEE-754 double precision and never executes input as JavaScript.
Frequently asked questions
What is the difference between DEG and RAD?
DEG interprets angles in degrees, RAD in radians.
How do I calculate an nth root?
Use root(x, n), for example root(32, 5).
What is the difference between ln and log?
ln uses base e, log base 10 and log2 base 2.
Why is sqrt(-1) unavailable?
This calculator works only in the real number domain.
What does Ans mean?
Ans is the last successful result in the current session.
What do SCI and ENG mean?
SCI uses scientific notation; ENG uses exponents divisible by three.
Can it solve equations?
No. It evaluates numeric expressions and is not an algebra or CAS system.
