I have a function whose output is a vector. Each value in the vector contains + or - operation as below.

5.39616521085160 + 0.00000000000000i

9.07848311879947 + 0.00000000000000i

18.6990064418951 - 0.609255622508561i

26.0039095870120 - 0.440617301529825i

34.9180935616170 - 1.38243566324103i

39.6501427984753 - 1.20885046059516i

How can I remove the operation sign and the values after the operations sign to get

5.39616521085160

9.07848311879947

18.6990064418951

i is the imaginary unit, sqrt(-1). Your answers are complex numbers, so it wouldn't really make sense to set i to 1.
