### eulerAngles\(\) function
#### <code>glm.<code>**eulerAngles**(**x**: *quat*) -\> *vec3*</code></code>
  Returns euler angles, pitch as x, yaw as y, roll as z\. The result is expressed in radians\.
### mat3\_cast\(\) function
#### <code>glm.<code>**mat3_cast**(**x**: *quat*) -\> *mat3*</code></code>
  Converts a quaternion to a 3 x 3 matrix\.
### mat4\_cast\(\) function
#### <code>glm.<code>**mat4_cast**(**x**: *quat*) -\> *mat4*</code></code>
  Converts a quaternion to a 4 x 4 matrix\.
### pitch\(\) function
#### <code>glm.<code>**pitch**(**x**: *quat*) -\> *float*</code></code>
  Returns pitch value of euler angles expressed in radians\.
### quatLookAt\(\) function
#### <code>glm.<code>**quatLookAt**(**direction**: *vec3*, **up**: *vec3*) -\> *quat*</code></code>
  See quatLookAtRH\.
### quatLookAtLH\(\) function
#### <code>glm.<code>**quatLookAtLH**(**direction**: *vec3*, **up**: *vec3*) -\> *quat*</code></code>
  Build a left\-handed look at quaternion\.
### quatLookAtRH\(\) function
#### <code>glm.<code>**quatLookAtRH**(**direction**: *vec3*, **up**: *vec3*) -\> *quat*</code></code>
  Build a right\-handed look at quaternion\.
### quat\_cast\(\) function
#### <code>glm.<code>**quat_cast**(**x**: *mat3*) -\> *quat*</code></code>
  Converts a pure rotation 3 x 3 matrix to a quaternion\.
#### <code>glm.<code>**quat_cast**(**x**: *mat4*) -\> *quat*</code></code>
  Converts a pure rotation 4 x 4 matrix to a quaternion\.
### roll\(\) function
#### <code>glm.<code>**roll**(**x**: *quat*) -\> *float*</code></code>
  Returns roll value of euler angles expressed in radians\.
### yaw\(\) function
#### <code>glm.<code>**yaw**(**x**: *quat*) -\> *float*</code></code>
  Returns yaw value of euler angles expressed in radians\.
