why don't you explain "psrf" ?

In any case, 1.07+0i is "1.07 + 0i", a complex number with 0
imaginary part and indeed quite close to the real number "1".
I guess that whoever wrote the function you are using (unknown to us)
could improve his/her code by only return Re(*), the real part,
if that (real numbers) is what is expected here.
