Number System
A signed number in $2′s$ compliment notation with $16−$bit register $P=DFA0$ What is the value of $P∗4$? I have tried $P∗4=0111111010000000$ but sign bit changed from $1$ to $0$. What is wrong with my solution?

Number System Interconversion
Can all the values in decimal be finitely represented in binary, hexadecimal and octal system and vice versa? I know 0.2 cannot be converted to the binary form which has a finite representation. Any other such number which cannot be converted from one of the number systems to other?

pls someone explain How to left shift this number ? 1010110<<2 Answer 1: shifting to the left means adding extra 0's as rightmost bits so in this case it means 101011000 now digit will be 1011000 but 1010110 represents 86 in decimal and left shift by 2 means multiply with 4 to the decimal number and now result 344 =101011000 now m confused ?

[COA] Floating point arithmetic
IEEE 754 32 bit representation for reference: 1. For the demoralized numbers,why the exponent is 126 and not 127? For 0 we say it is Mantissa=0 and B.E=0, so we get 0*2^0127=0,but for any number that is having bias exponent ... 128) comes under overflow and underflow condition.I mean if i am 0 or infinity or NAN then can i say that system is overflow/underflow?
