gistfile1.txt

CODE:

const a = [-0.0000064798259700182825, -0.0013201627880334854, 0.0000027575993044592906, 0.9999991059303284]
rigidBody.setRotation(new RAPIER.Quaternion(a[0], a[1], a[2], a[3]))
const r = rigidBody.rotation()
console.log("before:", a)
console.log(" after:", [r.x, r.y, r.z, r.w])

OUTPUT:

before: (4) [-0.0000064798259700182825, -0.0013201627880334854, 0.0000027575993044592906, 0.9999991059303284]
 after: (4) [-0.000006479826424765633, -0.0013201627880334854, 0.0000027575993044592906, 0.9999991059303284]
