Which Bit Of The Flag Register Is Set When Output Overflows To The Sign Bit? |
|
Answer» The 2nd bit of the flag register is set when output flows to the SIGN bit. This flag is also called as the overflow flag. Here the output of the signed number operation is too large to be ACCOMMODATED in 7 bits. For signed numbers the MSB is used to INDICATE the WHETHER the number is positive or negative. It is only used to detect errors in signed number operations. The 2nd bit of the flag register is set when output flows to the sign bit. This flag is also called as the overflow flag.
