I am processing an xml file from a third party, and it is full of co-
ordinates in the form 'x="165.0" y="229.0"'.

I don't mind using int(float(x)), I just wondered if there was a
shorter alternative.

If there is an alternative, I will be happy for it to raise an
exception if the fractional part is not 0.

Thanks
