This transfer is possible in two ways: direct transfer and using the decimal system.
first, let\'s make a direct transfer.
let\'s do a direct translation from hexadecimal to binary like this:
2CD.816 = 2 C D. 8 = 2(=0010) C(=1100) D(=1101). 8(=1000) = 1011001101.12
answer: 2CD.816 = 1011001101.12
now let\'s make the transfer using the decimal system.
let\'s translate to decimal like this:
2∙162+12∙161+13∙160+8∙16-1 = 2∙256+12∙16+13∙1+8∙0.0625 = 512+192+13+0.5 = 717.510
got It: 2CD.816 =717.510
Translate the number 717.510 в binary like this:
the Integer part of the number is divided by the base of the new number system:
717 | 2 | | | | | | | | | |
-716 | 358 | 2 | | | | | | | | |
1 | -358 | 179 | 2 | | | | | | | |
| 0 | -178 | 89 | 2 | | | | | | |
| | 1 | -88 | 44 | 2 | | | | | |
| | | 1 | -44 | 22 | 2 | | | | |
| | | | 0 | -22 | 11 | 2 | | | |
| | | | | 0 | -10 | 5 | 2 | | |
| | | | | | 1 | -4 | 2 | 2 | |
| | | | | | | 1 | -2 | 1 | |
| | | | | | | | 0 | | |
 |
the Fractional part of the number is multiplied by the base of the new number system:
 |
0. | 5*2 |
1 | .0*2 |
the result of the conversion was:
717.510 = 1011001101.12
answer: 2CD.816 = 1011001101.12
