Decimal number -5 represented as a halfword in Hexadecimal notation is?
Alright, let's forget the - for a while
convert 5 to binary.
2.5 absolute value=2
1 absolute value=1
0,5 absolute value=0
2*2=4 and 5-4=1
2*1=2 and 2-2=0
2*0=0 and 1-0=1 <--(last digit) = 101
complete the binary number by placing a 0= 0101.
Now as you might know HW = 2 bytes and 1 byte is 8 bits
so to to complete you should place 0000 0000 0000 before your result:
0000 0000 0000 0101
Let's not forget about the - though...
you'll have to invert your result
0000 0000 0000 0101=
1111 1111 1111 1010
and increment it by 1=1111 1111 1111 1011 and there is your result...
You could check your result this way:
0000 0000 0000 0101
+1111 1111 1111 1011
1 0000 0000 0000 0000
The first bit defines if your decimal has a + or - (1=- and 0=+)
The rest is simple...
(1111=F) (1111=F) (1111=F) (1011=B)=FFFB (hex HW)
There is basically one way to write hexadecimal numbers. Of course, the numbers represent information, and this information can be represented in may other ways; some of them are in binary (4 binary digits for each hexadecimal digit), in decimal, or each byte as as decimal number (as in the dotted decimal notation used for IP version 4 numbers).
Each hexadecimal digit represents four binary digits (bits) (also called a "nibble"), and the primary use of hexadecimal notation is as a human-friendly representation of values in computing and digital electronics. For example, binary coded byte values can range from 0 to 255 (decimal) but may be more conveniently represented as two hexadecimal digits in the range 00 through FF. Hexadecimal is also commonly used to represent computer memory adresses.
Yes. We could use decimal notation but hexadecimal is more convenient because it requires fewer digits and more closely reflects the way the machine addresses memory using its native binary notation. For instance, a 64-bit address in decimal requires 20 decimal digits (including leading zeroes) but only 16 hexadecimal digits. Moreover, the hexadecimal value can be easily translated into the actual binary value used by the machine because each hex digit maps 1:1 with every…
A: 1111111111 Learn with me first number is a 1 second is 2 third is 4 forth is 8,16,32,64.128.256.512,1024 and so forth if you add this numbers it will get the decimal equivalent, any zero along the way their number is not added but is skipped to the next number which is added as as its own value. For long values engineering uses octal notation group of 3 111=7 next 7,7,1 There is also hexadecimal…
Number System enables enumeration & quantitation of physical objects. For e.g. Binary, Octal, Decimal & Hexadecimal Number Systems. Number Code encodesunique characters with a number ineach Number System. For e.g.In ASCII Codecapital A is represented as 41 in hexadecimal, 65 in Decimal, 101 in Octal and 01000001 in Binary number System.
