[gnugo-devel] float's in surround.c

[Arend Bayer]

Dan, are you sure you aren't introducing new potential floating point
problems in surround.c?
It seems trivial to implicitly use rational numbers instead.

Yes I know, it would be pretty strange for a floating point calculation
to come up e.g. with

        15.0/5.0 = 2.99999998,

but...I wouldn't like to bet 10:1 that this cannot happen on any
platform.
