■Operation processing
• INT_TO_REAL, INT_TO_REAL_E
Converts word (signed) type data input to (s) into single-precision real type data, and outputs the operation result from (d).
s
1234
Word (signed) type
• DINT_TO_REAL, DINT_TO_REAL_E
Converts double word (signed) type data input to (s) into single-precision real type data, and outputs the operation result from
(d).
s
16543521
Double word (signed) type
The number of significant figures of single-precision real type data is approximately 7 since the data is processed in 32-bit
single precision. Accordingly, the converted data includes an error (rounding error) if an integer value is outside the range of -
16777216 to 16777215.
