Hi, 

I encountered an error for handling some rational numbers in guile 1.8.8 on OSX lion, although it works correctly on CentOS release 6.2 (Final), with guile 1.8.7. It is something like

guile> (define a 1e-21)
guile> a
1.0e-21
guile> (define a 1e-22)
guile> a
5.36275828919226e-19
guile> (define a 1e-25)
guile> a
6.28575819193153e-19
guile> (define a 1e-26)
guile> a
1.0e-26

My system is as follows.

Can you please try Guile 2.0.9?  I'm aware of many numerical bugs in
Guile 1.8.x, but we no longer support the 1.8 branch.  Guile 2.0 was
released over 2.5 years ago.

     Thanks,
       Mark
