Double value Xml parsing issue

 Hi,
I have some double value e.g 1937.966 in xml file, but after parsing through
"SAX2XMLReader XMLReaderFactory" my application getting it as 1937.95799,
which is wrong for my application.

Can i restrict this type of conversion, I need exact double figure as in xml
file.


*Thanks n Regards,**
Krushna*

Boris, this is not true. When I print out the original value 1937.966 in
different IEEE floating point representations, I get the following
results:

as double (64 bits): 1937.966000
as float  (32 bits): 1937.965942

HTH,
	Axel

Are you converting the text representation to the double type and
getting 1937.95799 or are you getting the text representation as
"1937.95799"? If it's the former, then it is most likely due to
1937.966 not being representable by double so you get the next
closest value.
