Subject: [Pdl-devel] unexpected results
Dear pdl folks,
doing $x=pdl(-3)
with PDL v2.081 we obtain $x**2-9==0
but, defining $z=-3+0*i
$z**2-9 =! 0
while
$z*$z-9 ==0
May be integer power are computed differently for real
but not for intrinsic complex? (loga
Dear pdl folks,

but, defining $z=-3+0*i
$z**2-9 =! 0
while
$z*$z-9 ==0
May be integer power are computed differently for real
but not for intrinsic complex? (logarithmically for any power)
