The asPoint() function must not do any changes to the geometry. I
suspect that the loss of precision happened when doing conversion to
string - check out this:

>>> "%f" % 123.4567890123456789
'123.456789'

for better precision, override the precision:

>>> "%.9f" % 123.4567890123456789
'123.456789012'
