Real lupnt::WrapToPi(Real angle)

Wrap angle in radians to [-pi, pi].

Wrap an angle to the range (-pi, pi] via atan2(sin(angle), cos(angle)).

Used pervasively in conversions/anomaly_conversions.cc (e.g. EccToMeanAnomaly, MeanToEccAnomaly) and time conversions (e.g. EarthRotationAngle) to keep angular quantities in a canonical range.

Parameters:

• angle – Angle in radians

• angle – Angle [rad]

Returns:

Wrapped angle in radians

Returns:

Wrapped angle [rad] in (-pi, pi]
