It doesn't. But as I had read that some people thought that the Android x86 version was using x87 (the Windows 32-bit version does use x87), I thought it made sense to say it.

Which makes me think I have always found the Lua score odd. ARM chips are doing very well on it (even a Cortex-A9 @ 1.4 GHz crushes a CT+ @ 2.0 GHz), and I wonder why.

The sum of the single-threaded benches is 4482 for the A9 and 4371 for the Z2580.
