Le mardi 10 juillet 2012 07:22:58 UTC+2, Ada novice a =E9crit :

> Believe me, for someone who do numerical computations on a daily basis, a=
n operation like V**2 is a NECESSITY. It&#39;s a pity that Ada does not off=
er such a facility. I do not blame those who stick to Matlab (or Fortran?) =
for doing numerical computations.
Wait... There are *such* facilities and several built-in operations *like* =
that:
http://www.ada-auth.org/standards/12rm/html/RM-G-3-1.html

Apparently it is not enough. But it is possible to make a proposal for the =
next standard (and shorter term, for the next GNAT version).

The snag with that *specific* operation, v**2 meaning "v(i)**2 for each i",=
 is that it is counter-intuitive from a linear algebra point of view. You w=
ould rather expect v**2 =3D v*v. Now another snag is should "*" be the dot =
or the cross product ?...

These kind of things are thought-out carefully before landing into an Ada s=
tandard...
