FAQ – Online Calculator

Q: Do trigonometric functions use degrees or radians?

A: By default, input is accepted in degrees (°) and internally converted to radians, so sin(90) = 1.

Q: How large can the numbers be?

A: The calculator uses float64 (IEEE 754) providing precision up to 15–17 significant digits. For very large or small results, exponential notation is used automatically.
