[text/scalc/01/ful_func.xhp#func_im_return_text not found].
If the result is a complex number with one of its parts (a or b) equal to zero, that part is not displayed.
=IMCOS("4-3i")
returns -6.58066304055116-7.58155274274654i.
=IMCOS(2)
returns -0.416146836547142 as a string. The imaginary part is equal to zero, so it is not displayed in the result.
