
For the string-to-integer conversion, the string is required to be the integer value such as ’123’, ’-
123’ and ’+123’. The string like ’M123’ is not allowed to convert to the integer. The conversion
examples are shown in the following table.
Input value
Output result
Data type Output value
‘123’ SINT 123
‘+123’ SINT 123
‘-123’ SINT -123
‘M123’ SINT
The conversion is not allowed and the original
value of the output variable is retained.

String to Real Number

Strings can be converted to real numbers. And some instructions are shown below.

For the string-to-real number conversion, the string is required to be the real number value such
as ’123’, ’-123.123’ and ’1.23e+5’. The conversion examples are shown in the following table.
Input value
Output result
Data type Output value
‘123’ REAL 123
‘-123.123’ REAL -123.123
‘1.23e+5’ REAL -1.23e+5
