TRUNC
IEC Operator: Converting from REAL to DINT. The whole number portion of the value
will be used.
Note: In »PLC Designer« V2.3 the TRUNC operator converts from REAL to INT. For this
reason when importing a V2.3 project TRUNC automatically will be replaced by
TRUNC_INT.
When you perform a type conversion from a larger to a smaller type, you risk losing
some information.
