Scientific Notation to Double

WilliamIde

Does anyone know of an elegant way to convert a string that has a number represented by scientific notation ( e.g.  .0340344E-4) to a double?  I and trying to normalize a set of shape files from different sources and one of my providers gave me a length field in sci notation.  All the others are doubles.  or strings as doubles.  (e.g. "23.5")  I can handle the second case.  Not sure how to do the first without resorting to "brute force" parsing.

Thanks

def SciNoteToFloat(x):
    '''Takes a string writen in scientific notation and
    returns a float'''
    x = x.lower()
    x = x.partition("e")
    return (float(x[0])) * (int("1" + "0" * (-1 * int(x[2]))))
mynum = "0.223E-7"
print SciNoteToFloat(mynum)
