[SciPy-user] do complex numbers default to double precision?

I have a matrix that is a function of a complex valued input. I am
trying to find that value of that input that drives the determinant of
the matrix to zero. I am searching for this value using fmin. The error
I am trying to minimize is the abs(det(complex matrix)). I don't seem
to be able to drive this error lower that roughly 9e-17, regardless of
the values for ftol and xtol I use.
Am I hitting some internal limitation? Are complex values by default
single or double precision?
