6.3 Data Conversion Instructions
• In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and an error code is stored into SD0.
• The following program converts the 64-bit floating decimal point type real number at D20 to D23 with BIN 16-bit data, and
stores the result at D0.
• The following program converts the 64-bit floating decimal point type real number at D20 to D23 with BIN 32-bit data and
