7.9 Real Number Instructions
Processing details
• These instructions convert the 32-bit unsigned binary data in the device specified by (s) to a single-precision real number,
and stores the real number in the device specified by (d).
• A single-precision real number is processed in 32-bit single precision, and therefore the effective number of digits is 24 bits
when it is represented in binary and is about 7 digits when represented in decimal. For this reason, if the integer value
exceeds the range from 0 to 16777215 (24-bit binary value), an error occurs in the converted value. The operation result is
an integer value in which the 25th bit from upper bits is rounded off.
Operation error
There is no operation error.
(1) Rounded down.
(2) Rounded off.
