The result is:

1.00000000000000000000000000000002

so the last digit is non zero, but less than 5.

My goal was to have a simple way to build the weekly snapshot
with my knowledge of *nix.  And it works more or less (when the
snapshot is too broken, I just skip it, if there is a simple
patch, I let my machine compile for a other night).
