Description:
The current float/double sort key generation is unneccessarily complicated, and poorly documented. It can be made simpler (and faster) by noticing that positive floats already sort correctly as ints, and doing some minor tweaks for negative numbers.

How to repeat:
N/A

Suggested fix:
N/A

Fixed in 8.0.1.

Code cleanup. No changelog entry needed.
