As Louis said, integer values are probably good enough.  But there are
a couple ways to coax a little more precision out of PS.   One is that
you can use RGB values -- at least they go 0-255 instead of 0-100.
Also if you have scanned 16-bit the Info palette has a 16 bit mode 
where the L values show 0-32768.
