2. 32-bit operation (DZONE and DZONEP)
The bias value specified by [
+1,
] or [
+1,
] is added to the input value specified by
[
+1,
], and output to the device specified by [
+1,
].
The bias value is added as shown below:
Caution
• When the output value overflows, it is handled as follows:
- In the 16-bit operation
The operation result is a 16-bit binary value with sign. Accordingly, if the output value is outside the
range from -32768 to +32767, it is handled as follows:
- In the 32-bit operation
The output value is a 32-bit binary value with sign. Accordingly, if the operation result is outside the
range from -2,147,483,648 to +2,147,483,647, it is handled as follows:
