How to interpret Pitch, Yaw , Roll on the orientation feature?

[vajos]

https://github.com/react-native-sensors/react-native-sensors/blob/master/docs/API.md#orientation-observableqx-number-qy-number-qz-number-qw-number-pitch-number-roll-number-yaw-number-timestamp-string

The documentation there just says "pitch, roll, yaw are calculated by iOS/Android. "

When i Try to use them

console.log("Pitch: " + pitch + " " + " Roll: " + roll + " " + "Yaw: "+ yaw);

I get this values:

I tried using radians_to_degrees for pitch roll and yaw and they are still different values to the android emulator values.

How do I get this values from your library ?

I just want to get the same values as I type into the emulator if i specify "Z-Rot: 90" I expect to get the value 90 on my App.
Or how do I Interpret this values I thought Pitch Yaw Roll are the same as X,Z,Y Rotation .
Would appreciate any help<3
