# XMMATRIX XMMatrixRotationY wants the angle in radians or degrees? DirectX

The documentation is totally unclear about it. And also what does" Angles are measured clockwise when looking along the rotation axis toward the origin" mean? Are they measured clockwise looking from where? Documentation: https://msdn.microsoft.com/en-us/library/windows/desktop/microsoft.directx_sdk.matrix.xmmatrixrotationy(v=vs.85).aspx

The convention of XMMatrixRotationY is the latter.
