Re: d3dx9: Implement D3DXFloat32To16Array and D3DXFloat16To32Array. (try 2)

[Rico Schüller]

Hi,

I have a small hint to the D3DXFloat32To16Array function. It seems that 
some values are handled in some other way.

A small test:
         D3DXFLOAT16 res;
         union p
         {
             float f;
             DWORD d;
         } x;

x.d = 0x33000800;
         D3DXFloat32To16Array(&res, &x.f, 1);
         ok(res.value == 1, "Failed %f %x\n", x.f, res.value);

This fails with the current implementation. It's not the only value, 
there are a couple of them which are of by one. This could be easily 
seen by loading both d3dx36.dll (wine and native) and comparing the 
values directly.

Cheers
Rico
