Minimum, Maximum, Average and Moving
Average outputs are output in FLOAT32 format.
Before they are processed further and converted
from FLOAT32 to INT32 or UINT32, the output
signal must be checked to determine whether it
is larger than INT32_Max or UINT32_Max. If it is
larger, data type UINT64 or INT64 should be
used.
