6 Explanation of Instructions and Functions
6.3 Data Designation Method
Floating decimal point data in CPU modules can be monitored with the monitoring function of a programming tool.
When floating-point data is "0", all data in the following range are turned to "0".
 Single-precision floating-point data: b0 to b31
 Double-precision floating-point data: b0 to b63
The setting range of floating decimal point data is as follows. (*1)
 Single-precision floating-point data: -2
 Double-precision floating-point data: -2
Do not specify "-0" in floating-point data (when only the most significant bit of the floating-point real number is "1"). (An
arithmetic error will occur if floating-point operation is performed with "-0".)
(*1) When a real number is out of range or when an invalid value is input, an arithmetic error occurs.
For the error details and the operation, refer to the operation details of each operation.
