Summary: status of small floats in xml-rpc ?
Initial Comment:
Hi,
I've been reading through the xmlrpclib.py code to see
that floats are marshalled the following way:
def dump_double(self, value, write):
write("<value><double>")
write(repr(value))
write("</double></value>\n")
dispatch[FloatType] = dump_double
Using repr() means that small or big floats, for
example, will be output using the exponent notation:
>>> repr(2**-15)
'3.0517578125e-05'
Unfortunately, the XML-RPC specification does not allow
this notation:
"At this time, only decimal point notation is allowed,
a plus or a minus, followed by any number of numeric
characters, followed by a period and any number of
numeric characters. Whitespace is not allowed. The
range of allowable values is implementation-dependent,
is not specified."
(http://www.xmlrpc.com/spec)
Thus floats marshalled using xmlrpclib may not be
readable using other XML-RPC implementations.
(I don't have any concrete data about this though)
