Introduction: When linking a double array to an integer array, values will be truncated. If the value
overflows, the integer array may be populated with random data.

Issue: The conversion behavior when linking a non-array double to a non-array integer is different
from the conversion behavior when linking a double array to an integer array.
If a non-array double is linked to a non-array integer, the value is rounded. If the value is too large to
fit in the integer, the user will receive an overflow error and the link will be left invalid.
However, if a double array is linked to an integer array, the values are truncated. If the value overflows,
the integer array will be populated with random data.

Impact: If a double array is linked to an integer array, the user may get unexpected results.
Resolution: Avoid linking double arrays to integer arrays. If it is necessary to link double arrays to
integer arrays, use extreme caution and make sure the conversion rules described above are
understood.
