Function Helmert7.rotationX

X-axis rotation, canonically stored in radians.

Angle!T rotationX() const pure nothrow @nogc @property @safe;

Example

Example reading the X rotation. 

import geodesy;
const transform = Helmert7!(double, HelmertConvention.positionVector)
    .fromArcSecondsAndPpm(1.0, 2.0, 3.0, 0.1, 0.2, 0.3, 0.4);
assert(transform.rotationX.radians != 0.0);
