Origin Ver. and Service Release (Select Help-->About Origin):
Operating System: Windows 10

I know it sounds too basic but I want to calculate impedance, that involves calculating the quotient of two columns of complex numbers (I mean, the quotient cell to cell) that I have got by using the fft() function. My problem seems to be with the imdiv() function (I am using OriginPro Trial version).

I type

=imdiv(2+3*i, -1+i)

in a cell. When I press INTRO, I've got an error "incorrecto numer of arguments passed to the function imdiv" and

=imdiv(2+3*i, -1+i)

has changed into

=imdiv(2+3*i. -1+i)

That is, the comma has been changed by a dot. Perhaps it has to do with the variable type (but I don't know how to fix it).

Menu Tools > Options > Numeric Format:

Set the Separators as "1,000.0" should solve the problem.

Edit: imdiv(2+3*i, -1+i) is different from imdiv(2+3i, -1+1i). "i" in the former one is the row index. You should not use Cell Formula in this case for complex number can be displayed in one cell correctly unless the format is numeric and the data type is complex while cell formula works only when the format is text & numeric.
