`quaternion-y-rotation``ANGLE``#!optional``RESULT`procedureReturn the quaternion corresponding to a rotation of

`ANGLE`radians around the y-axis. If the quaternion`RESULT`is given, it will be modified to contain the result. If`RESULT`is`#t`the returned value will be an f32vector located in non-garbage-collected memory (the memory will still be freed when there are no more references to the matrix). If`RESULT`is not provided, the returned value will be an f32vector located in normal garbage collected memory.
