......................................................................

IMPALA-3603 [DOCS] Document handling of NaN values

Added information in the "DOUBLE Data Type" (impala_double.html)
and the "FLOAT Data Type" (impala_float.html) topics about
how Impala handles NaN values.

This information has been added to the subsection
"Usage Notes:" in each topic:

"Impala does not evaluate NaN (not a number) values as
equal to any other numeric values, including NaN. For
example, the following statement, which evaluates
equality between two NaN values returns 'false':

SELECT CAST('nan' AS DOUBLE|FLOAT)=CAST('nan' AS DOUBLE|FLOAT);
