Calculator results

Our calculator uses standard formulas and floating-point arithmetic. Very large, very small or repeating numbers are rounded for display. Angle functions use degrees or radians as shown on screen.

Games and school network filtering

We do not guarantee that any game, or the Code Mode shortcut, will remain reachable at any specific school, network or point in time. Network filters change without notice, and a filter may block this site outright at any point. Following your school's or organisation's own acceptable-use policy is your responsibility, not ours.

Not professional advice

Nothing on this site is financial, legal, academic or professional advice, and we are not a licensed adviser or a school. For decisions with real consequences, consult a qualified professional or the relevant policy at your own institution.

Third-party content

Games are supplied by a licensed third-party distributor and may include their own advertising or in-game content that we do not control and are not responsible for.

No liability

We are not responsible for loss arising from reliance on our results, or from playing any game accessed through this site, including any consequence of using it in a setting where games are not permitted. See the Terms of Use.
