Formula and methodology
Formula: Angle radians=arctan(value); angle degrees=arctan(value)×180/π.
The principal inverse-tangent branch is shown in both common angle units.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Tangent value — minimum -1000000000; maximum 1000000000
Worked example
| Input | Value |
|---|---|
| Tangent value | 1 |
arctan(1)=0.7854 radians=45 degrees.
Assumptions and limits
- The input is a finite real ratio.
- The principal angle range is strictly between negative π/2 and π/2 radians.
- Quadrant information from separate x and y components, periodic branches, and measurement uncertainty are not modeled.
