In Python3.2, calling math.erfc with a value in [-27.2, -30) raises an OverflowError: math range error. This is inconsistent with the erfc function from scipy (scipy.special.erfc) as well as with the C99 function by the same name, both of which return 2. I suspect that this is the result of the cutoff for the use of the continuing fraction approximation of erfc beginning when abs(x) > 30, but I'm not sure. Is this desired behavior or should I file a bug report?
