exp(A) gives zero in the first argument

When I compute for example
exp([71 307])
on matlab (on my laptop version) I get
ans =
1.0e+133 *
0.0000 2.1301
Which seems pretty unreasonable to me as 71 is not that big and of course not bigger than 307.
Also if I put the same computation on octave online I get
ans =
6.8377e+30 2.1301e+133
which makes tottaly sense.
Do you know what is going wrong?

Try this:
format longE
exp([71 307])
producing:
ans =
6.837671229762744e+30 2.130129192828224e+133

There is no bug. The default format is short. You can change it in the Preferences to something else, or change it specifically for one calculation or a set of calculations as I did here, then (if you want to), change it back to a previous definition. The chosen format will be whatever you chose for it when you start MATLAB, and if you change it, the change will remain until you change it to something else. See the documentation I linked to for details.
