Subject: octave: exp(-Inf)!=0
To: submit@bugs.debian.org
Bcc:
X-Mailer: bug 3.1.5

Package: octave
Version: 2.0.13-6

Hi,

octave does calculate exp(Inf) exp(-Inf) wrongly:

exp(Inf) -> NaN
exp(-Inf) -> NaN

It would be correct and even more matlab compatible
to yield:

exp(Inf) -> Inf
exp(-Inf) -> 0

Regards,
Ferdinand.

  * Bump Standards-Version to 3.1.1 (nicely in sync with our own version :)

    and provide use our own implementation of putgrent=20
