Processing details
■Operation processing
• STR_TO_INT, STR_TO_INT_E
Converts string type data input to (s) into word (signed) type data, and outputs the operation result from (d).
High-order byte
String 1st word ASCII code of ten-thousands place
2nd word ASCII code of hundreds place ASCII code of thousands place
3rd word ASCII code of units place ASCII code of tens place
4th word 00 (Indicates the end of the character string.)
H
The value to be input to (s) is string type data within the following range.
ASCII code: '30H' to '39H', '20H', '2DH', and '00H'
String type data: '-32768' to '32767'
• STR_TO_DINT, STR_TO_DINT_E
Converts string type data input to (s) into double word (signed) type data, and outputs the operation result from (d).
High-order byte
String 1st word ASCII code of billions place
2nd word ASCII code of ten-millions place ASCII code of hundred-millions place
3rd word ASCII code of hundred-thousands place ASCII code of millions place
4th word ASCII code of thousands place ASCII code of ten-thousands place
5th word ASCII code of tens place
6th word 00
H
Indicates the end of the character string.
