This seems to be the cause:

The function bug_report() provides bug reporting information.
(%i1) float(%e^(10000/3));
(%o1) i.nfE-16128
(%i2) float(%e^10000);
(%o2) 8.806818225658306b4342
For some reason, Maxima doesn't "promote" the first result to a big float, but it does do so with the second one.

Note that since the float-to-bigfloat promotion code has been moved to branch promote-float-to-bigfloat and reverted on master, this bug report is no longer applicable. I've marked it "wont-fix" to distinguish it from "closed".

I just came across something very strange: When doing
abs(%e^(10000/3)+1);
, I get the error "bfloat: attempted conversion of floating-point infinity."OK, you might think, it's just a huge number. But when removing the
/3
, it works! It also works when removing the+1
.
