ANY_TO_LWORD structured text example
bres := ANY_TO_LWORD (true); | (* bres is 1 *) |
tres := ANY_TO_LWORD (t#0s46ms); | (* tres is 46 *) |
mres := ANY_TO_LWORD ('0198'); | (* mres is 198 *) |
Instruction behavior changes starting from firmware revision 23.012
When converting REAL or LREAL values to the LWORD data type, the following rules apply:
- Positive values
- Values from 0 through 2⁶³ − 1 can be converted to the LWORD data type.
- Values exceeding 2⁶³ − 1 are clamped to 2⁶³ − 1.
- Negative values
- Values from −1 through −2⁶³ can be converted to the LWORD data type.
- Values smaller than −2⁶³ are clamped to 2⁶³.
