When power is received, the Truncate functions TRUNC_DINT and
TRUNC_INT round a floating-point (REAL) value down respectively to the
nearest signed double-precision signed integer (DINT) or signed single-
precision integer (INT) value. TRUNC_DINT and TRUNC_INT output the
converted value to Q. The original data is not changed.
