[Jscheme-devel] (eq? 128 128) => #f

[Geoffrey K. <ge...@kn...>]

I ran into this while calculating azimuths.

 > (eq? 180 180)
#f
 > (= 180 180)
#t
 > (eq? 0 0)
#t
 > (eq? 1 1)
#t
 > (eq? 2 2)
#t
 > (eq? 3 3)
#t
 > (eq? 180 180)
#f

After poking around, I found this:

 > (eq? 127 127)
#t
 > (eq? 128 128)
#f
 > (eq? -127 -127)
#t
 > (eq? -128 -128)
#f

For now I'll use = instead of eq?.  I was just wondering if this was 
documented.
