This was fixed for XNAMath 2.03
from directxmath.
The ARM 32-bit platform using ARMv7 does not have an explicit divide operation in ARM NEON, so XMVectorDivide
is implemented with 2 iterations of Newton-Raphson refinement of the reciprocal
from directxmath.
ARM64 which requires ARMv8 has a new ARM NEON intrinsic vdivq_f32
which can be used to implement XMVectorDivide
rather than using the multiply-by-reciprocal
from directxmath.
