I just wanted to ask you, did you ever used the floating-point DCT method?
The following differences are just compared between DCT float and DCT int (slow) method.

Pro:
- more accurate (depend on CPU)
- the difference should be not visible
- lower size

You means DCT float (slow)

There is only one float mode, so why should I add slow?

If you relate to the Streaming SIMD Extensions (SSE),
the common Applications (for example XnView) support just the one.
