Hi everyone,

The next issue is really driving me mad.

In a mapping I'm calling a function in an external assembly with does
some calculations. Sometimes the result of the calculations is a very
tiny number, f.e. -0.0000000000072759576141834259. The function uses
the datatype 'double'. In the mapping this value results in NaN. Why is
that?

What is the datatype of the schema element you are mapping to?

(fyi - assigning the number below to a double will result in some loss of
precision - you have 17 significant digits, whereas doubles are good for
15.)

Hi,

i think this is based on the "XSD" part of the definition, not the
return type of the external assembly.

Hope this helps,
