Operator: TRUNC_INT

The IEC operator is used for converting the REAL data type into the INT data type. CODESYS takes only the integer part of the number.

Tip

TRUNC_INT corresponds to the TRUNC operator in CoDeSys V2.3, and it is used automatically at this point when importing V2.3 projects. Note the change function of TRUNC in CODESYS V3.

If CODESYS cannot represent the input value by a DINT or INT, then the result of this function is undefined. The behavior of such input values is platform-dependent.

Example 178. Example

ST

iVar := TRUNC_INT(1.9); (* Result: 1 *)

iVar := TRUNC_INT(-1.4); (* Result: -1 *)
