floats in bigloo

Hi Manuel and all,

We are porting our software previously based on bigloo 3.x  to the latest bigloo-4.3a-last. It works.
But our regressions suites are completely flagged, because floats representation has changed:
If I do :  (* 1.3 2.45)  with bigloo 3.x, then it returns 3.185
But if I do the same with bigloo 4.3a then it returns  3.1850000000000005
Is there a way to come back to previous representation ? via a setting in configure or something else ?
Or could you suggest a patch we could do in our copy of bigloo ?
Many thanks, regards,
Michel.
