You're exceeding the precision of a float or double (whichever is used
for reals):
guile> 40816513889983671.0
40816513889983700.0 <--- rounded up
guile> 40816513889983671
40816513889983671 <--- integers are not rounded
FWIW, Bigloo and Ikarus behave similarly, and I don't think there's much
that can be done.
Thanks,
Ludovic.
