Explain how to determine if a number is negative in the following representations sign magnitude twos complement biased.?
To determine if a number is negative in different representations: Sign Magnitude: Check the most significant bit (MSB); if it is 1, the number is negative. Two's Complement: Again, look at the MSB; if it is 1, the number is negative. Biased Representation: Subtract the bias (typically 127 for 8-bit representation) from the actual value; if the result is less than zero, the number is negative.
Twos complement of a given 3 or more bit binary number of non-zero magnitude is the same the original number if all bits except the?
ANSWER: MSB IS 1 In the 2's complement representation, the 2's complement of a binary number is obtained by first finding the one's complement (flipping all the bits), and then adding 1 to the result. This representation is commonly used to represent signed integers in binary form. Now, if all bits except the sign bit are the same, taking the 2's complement of the binary number will result in the negative of the original number. The sign bit (the leftmost bit) is flipped, changing the sign of the entire number. For example, let's take the 4-bit binary number 1101 The 2's complement would be obtained as follows: Find the one's complement: 0010 Add 1 to the one's complement: 0011

How do you represent -123 in twos complement in 10 bits register?
-123 = 11 1000 0101 [I presume the number 123 is in decimal] First write the positive number in binary using 10 bits (I've split it into groups of 4 bits to make it easier to read): 123 = 00 0111 1011 Convert to 1s complement by inverting all bits (any 0 => 1, any 1 => 0): 00 0111 1011 => 11 1000 0100 Finally add 1 to get 2s complement: 11 1000 0100 + 1 = 11 1000 0101 Thus the 2s complement of the negative number: -123 = 11 1000 0101 This can also be expressed in hexadecimal: -123 = 0x385 Or in octal (easy to convert if the binary number is first written in groups of 3 bits): -123 = 1 110 000 101 = 01605 [I've used C notation for the hexadecimal and octal numbers.]
Subtract the hexadecimal number 1234 from DA57 using twos complement addition method?
(1234)hex=(0001 0010 0011 0100)2 (DA57)hex=(1101 1010 0101 0111)2 Taking, (1234)hex=(0001 0010 0011 0100)2 =(1110 1101 1100 1011) -1s complement =(1110 1101 1100 1100) -2s complement Now ,add 2s complement of (1234)hex with (DA57)hex, we get 1110 1101 1100 1100 + 1101 1010 0101 0111 1 1100 1000 0010 0011 There is a Carry bit Since,carry is generated.so,no is negative Then take 2s complement of above no.Thus ,we get 0011 0111 1101 1101=(37DD)hex (1234)hex -(DA57)hex =37DD)hex

How do you write a program to determine whether a number is odd or even counter?
For positive integers, if the least significant bit is set then the number is odd, otherwise it is even. For negative integers in twos-complement notation, if the least significant bit is set then the number is odd, otherwise it is even. Twos-complement is the normal notation, allowing a range of -128 to +127 in an 8-bit byte. For negative integers in ones-complement notation, if the least significant bit is set then the number is even, otherwise it is odd. Ones-complement is less common, allowing a range of -127 to +127 in an 8-bit byte, where 11111111 is the otherwise non-existent value -0 (zero is neither positive nor negative). Ones-complement allows you to change the sign of a value simply by inverting all the bits. Twos-complement is the same as ones-complement but we also add one. Thus the twos complement of 0 is 0 because 11111111 + 1 is 0 (the overflowing bit is ignored). 11111111 then becomes -1 rather than the non-existent -0.

Why do you get an even number when you add two even numbers?
An even number is always some quantity of 'twos' (2's), and any quantity of twos is an even number. The first even number is a quantity of twos, and the second even number is another quantity of twos. When you add the first quantity of twos to the second quantity of twos, you get a new quantity of twos. Since the new quantity of twos is a quantity of twos, it's an even number.
10 Why is twos complement usually used to represent integers?
The advantage of the two's complement method is that the procedure for adding or subtracting numbers is the same, whether the numbers are positive or negative. This makes the hardware for managing these numbers simpler.
Twos complement of a given 3 or more bit binary number of non-zero magnitude is the same the original number if all bits except the?
ANSWER: MSB IS 1 In the 2's complement representation, the 2's complement of a binary number is obtained by first finding the one's complement (flipping all the bits), and then adding 1 to the result. This representation is commonly used to represent signed integers in binary form. Now, if all bits except the sign bit are the same, taking the 2's complement of the binary number will result in the negative of the original number. The sign bit (the leftmost bit) is flipped, changing the sign of the entire number. For example, let's take the 4-bit binary number 1101 The 2's complement would be obtained as follows: Find the one's complement: 0010 Add 1 to the one's complement: 0011
How do you write a basic program find whether number is even or odd if even display its square and if odd display its cube?
Divide that number into 2 using modulus division. Modulus division get the remainder of the division. If it has no remainders, then it's an even number. If not, then it's an odd number. Here's a pseudo code of the program. ALGORITHM ODD_EVEN INPUT (number) IF (number MOD 2 == 0) THEN DISPLAY ("Even") ELSE DISPLAY ("Odd") END IF END ODD_EVEN Amendment: You did ask for a BASIC program: 10 INPUT X: IF X = 999 THEN STOP 20 PRINT X;: IF X/2 = INT(X/2) THEN PRINT "EVEN" ELSE PRINT "ODD" 30 GOTO 10
How do you programme Twos complement in binary in c?
int complement (int n) { return -n; } or int complement (int n) { return ~n+1; } both does the same thing.

What is unsigned data types in turbo c?
The same as an unsigned type in any other implementation of C. An unsigned type is an integer that is guaranteed positive. Normally, the most-significant bit of an integer denotes the sign (positive or negative). Unsigned types use this bit to denote value, effectively doubling the range of positive values over that of the signed equivalent. For instance, a signed char has a guaranteed range of -127 to +127 while an unsigned char has a guaranteed range of 0 to 255. Note that a signed char typically has a valid range of -128 to +127, however this is only true on systems that utilise twos-complement notation. Those that use the older ones-complement notation have two representations for the value zero (one positive, one negative). Ones-complement simply inverts all the bits of a value to switch the sign of a value, whereas twos-complement adds the value 1 after inverting all the bits. The value zero is denoted as 00000000 in binary. Inverting the bits creates 11111111, which is minus zero on a ones-complement system and -1 on a twos-complement system. -1 + 1 is 0, hence we add 1 on a twos-complement system.
