Multiplication by 0: nonzero in versions 8 and 9
Posted:

Hello ,
I have noticed that in all Mathematica versions <8, multiplying a real or complex number by the integer 0 gives 0, but in versions 8 and 9
Times[0, 0.567] gives 0.
and
Times[1.23 + I 2.45, 0] gives 0. + 0. I
I don't know what prompted this change but it is definitely wrong: the zero property of multiplication holds for real and complex numbers also (see https://en.wikipedia.org/wiki/Multiplication#Properties) .
