----------------------------------------
Summary: RS_BandAsArray truncates the decimal part of float/double
pixel values.
Key: SEDONA-362
URL: https://issues.apache.org/jira/browse/SEDONA-362
Project: Apache Sedona
Issue Type: Bug
Affects Versions: 1.4.1
Reporter: Kristin Cowalcijk
Fix For: 1.5.0
When retrieving array from float/double bands using {{RS_BandAsArray}}, the
band data were truncated. Here is an example:
{code:sql}
WITH t AS (SELECT RS_AddBandFromArray(RS_MakeEmptyRaster(1, 2, 2, 0, 0, 1),
ARRAY(1.1, 2.2, 3.3, 4.4), 1) rast)
SELECT RS_BandPixelType(rast, 1), RS_BandAsArray(rast, 1) as band FROM t
+-------------------------+--------------------+
|rs_bandpixeltype(rast, 1)| band|
+-------------------------+--------------------+
| REAL_64BITS|[1.0, 2.0, 3.0, 4.0]|
+-------------------------+--------------------+
{code}
While the expected result is {{[1.1, 2.2, 3.3, 4.4]}}.
