15 TYPE CONVERSION FUNCTIONS
15.19 Converting INT to DWORD
15.19 Converting INT to DWORD
INT_TO_DWORD(_E)
These functions convert INT type data to DWORD type data.

■Descriptions, types, and data types
Processing details
■Operation processing
• These functions convert the INT type data input to (s) to DWORD type data and output from (d).
• Each of high-order 16 bits becomes "0" after data conversion.
• A value input to (s) is the INT type data value.
■Operation result
1. Function without EN/ENO
The operation processing is executed. The operation output value is output from (d).
2. Function with EN/ENO
The following table lists the execution conditions and operation results.
*1 When FALSE is output from ENO, data output from (d) is undefined. In that case, modify a program so that the data output from (d) is
not used.
Operation error
There is no operation error.
