자주 묻는 질문

Are trig functions in degrees or radians?

Degrees — sin(30) means the sine of 30 degrees, which matches how most people expect a calculator to behave.

What does log vs ln mean?

log() is base-10 logarithm; ln() is the natural logarithm (base e).

Is factorial supported for large numbers?

Factorial works for non-negative integers up to 170 before the result exceeds standard floating-point range.

What inputs does the Scientific Calculator need?

You'll need to provide: Expression. All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.

How accurate is the Scientific Calculator?

The Scientific Calculator applies the formula exactly as calculated — Same arithmetic engine as the basic calculator, extended with sin/cos/tan (degrees), log (base 10), ln (natural log), sqrt, factorial (!), and the constants π and e. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.

Is the Scientific Calculator free to use?

Yes, the Scientific Calculator is completely free, requires no signup, and runs instantly in your browser.

The Scientific Calculator uses a real, verifiable formula — Same arithmetic engine as the basic calculator, extended with sin/cos/tan (degrees), log (base 10), ln (natural log), sqrt, factorial (!), and the constants π and e. — so results are accurate every time, not an approximation.
