First of all it will be converted to binary number and that is
0.0000000000000000000000000000000000000000000000000000000011110100011001010110001100000011110001110001
i.e, 1.1110100011001010110001100000011110001110001 * 2-57, now exponent's value is -57.
sign is positive and mantissa is 1110100011001010110001100000011110001110001.
now we can write
Sign |
Exponent | Mantissa |
|||
0 | 01111000110 |
|
and in hexa decimal the number is
0x3C6E8CAC6078E200
Now, in order to write it in double precision floating point format we need to write this number in normalized form
So the answer will be
1) 132.487359893280127146769272484e-19
2) 111.1010001100101011000110000001111000111000100000000000000000000000000000000000000000000000000000000000000000
3) 1.1110100011001010110001100000011110001110001 *2-57
4) 1110100011001010110001100000011110001110001000000000
5) Biased exponent (in binary): 01111000110
Biased exponent (in decimal): 966
6) 0011110001101110100011001010110001100000011110001110001000000000
7) 0x3C6E8CAC6078E200
If you like the answer, please give a thumbs up.Thanks

2.4 Recall from class that MATLAB uses standard (IEEE) double-precision floating point notation: 52 bits 11 bits where each bit b Any Number- +/- (1.bbb...bbb)2 x 2 (bbb..bb2 102310 represents the digit 0 or 1. That is, the mantissa is always assumed to start with a 1, with 52 bits afterwards, and the exponent is an eleven bit integer (from 000..001 to 111...110) biased by subtracting 1023 Well, in "my college days" the standard was single-precision floating point notation in...

IEEE 754-2008 contains a half precision that is only 16 bits wide. The leftmost bit is still the sign bit, the exponent is 5 bits wide and has a bias of 15, and the mantissa is 10 bits long. A hidden 1 is assumed. Write down the bit pattern to represent -1.6875 X 100 assuming a version of this format, which uses an excess-16 format to store the exponent.
