     IMPRODUCT() is suppose to calculate products of complex numbers.
However, its answers are not correct: only the real portion of the
complex numbers seem to be used.
          =IMPRODUCT(2+i2,2-i2)
          = 2*2+2*i2-2*i2-i2*i2
          = 4 +i4 -i4 -(4)          [i2*i2=-4]
          = 8
But Calc lists the answer as 4.

     Are there any complex functions that really work other than
IMREAL()? (It only reads the real part of a complex number.

I confirm this result with 3.5.4.2, Ubuntu 12.04

According to the help document
"http://help.libreoffice.org/scalc/SC_HID_AAI_FUNC_IMPRODUCT?Language=en_US&System=WIN&Version=3.5#bm_id3150661";,
the formula should be IMPRODUCT("2+2j","2-2j")
Thank you.
