The following seem to be related. 1/5000 is 2e-4; 1/1 is 1e-4 and so
all these lines should give the same result of -4. The conversion
"asExactFraction", which is called from the Float.st version of
floorLog:, causes a -5 answer which is wrong:

Hi Bill,
I think the ZeroDivide exception is unrelated, and caused by your gst being
compiled with option -pie (the default in many distros). If so, you would
get the same exception for 0.05 and many other numbers. Try compiling gst
with -no-pie to see if the exception goes away.

Hi,
The float 1e-4 gets too many zeros when printed. This happens on version
3.2.5 and on the current master branch at git://git.sv.gnu.org/smalltalk.git,
on both 32-bit and 64-bit.
Example:
st> x := 1e-4
0.1
st> x+x
0.0002
Kind regards,
Tommy
