Processing details
■Operation processing
• INT_TO_BOOL, INT_TO_BOOL_E
Converts word (signed) type data input to (s) into bit type data, and outputs the operation result from (d).
When the input value is 0, FALSE is output in bit type data.
When the input value is other than 0, TRUE is output in bit type data.

Word (signed) type
• DINT_TO_BOOL, DINT_TO_BOOL_E
Converts double word (signed) type data input to (s) into bit type data, and outputs the operation result from (d).
When the input value is 0, FALSE is output in bit type data.
When the input value is other than 0, TRUE is output in bit type data.
