Formatting of Complex Numbers in Google Sheets

Question

How can complex numbers be formatted in Google sheets? If for instance I have the following complex number in a cell, with both real and imaginary part too long for my needs,

=COMPLEX(1.23456789, 0.987654321)

which would be displayed as

1.23456789+0.987654321i

where is the format accessible so that it is displayed as in the following?

1.23+0.99i

Answer 1

this maybe:

=COMPLEX(ROUND(1.23456789,2), ROUND(0.987654321,2))
