Enter a number:
His number system:
Binary
Ternary
Octal
Decimal
Hexadecimal
Binary-decimal
Other
Additional
Signed
Direct
One complement
Two complement
Unsigned
1 byte
2 byte
4 bytes
8 bytes

You specified that your number is in the additional code. For further conversion, you need to get a direct number code. Therefore, let\'s perform the conversion from additional code to direct code.

to do this, first perform the conversion from the additional code to the reverse by subtracting 1 bit, then get the direct code by inverting all the bits except the signed one.

01000001 twos-complement
-1 -1 bit
11000000ones complement
10111111direct code
got It:10111111

let\'s translate to decimal like this:

1∙27+0∙26+1∙25+1∙24+1∙23+1∙22+1∙21+1∙20 = 1∙128+0∙64+1∙32+1∙16+1∙8+1∙4+1∙2+1∙1 = 128+0+32+16+8+4+2+1 = 19110

got It: 101111112 =19110
