Math.Tests.WrapAngle ​

Wraps constant and time-varying angles to the interval ]-π, π].

Connects a constant source with value 4.0 (≈ 1.27π) to a WrapAngle block with default positiveRange=false and verifies the output is wrapped to ]-π, π]. Expected: 4.0 - 2π ≈ -2.2832. A second WrapAngle block is driven by a sine wave (amplitude 6 rad) that sweeps several periods of ±π, exercising the wrapping across negative and positive angles.

Usage ​

BlockComponents.Math.Tests.WrapAngle()
