Kikamilisho cha Mbili

Kijalizo cha mbili ni operesheni ya hisabati inayotumiwa kuwakilisha nambari hasi katika mifumo ya binary. Inatumika sana katika kompyuta kwa sababu hurahisisha shughuli za hesabu kama vile kuongeza na kutoa.

Ili kubadilisha nambari chanya kuwa mwenzake hasi katika nyongeza mbili:

  1. Badilisha nambari kuwa binary.
  2. Invert all the bits (change 0 to 1 and 1 to 0).
  3. Ongeza 1 kwa matokeo ya ubadilishaji.

Ili kubadilisha nambari ya nyongeza ya mbili hasi kuwa desimali:

  1. Geuza bits zote.
  2. Ongeza 1 kwa matokeo ya ubadilishaji.
  3. Badilisha matokeo kuwa decimal na uambishi awali kwa ishara hasi.

Mfano: 8-bit Two's Complement

Positive Number (5):

0000 0101 (binary)

Negative Number (-5):

1111 1010 (inverted bits of 5)

1111 1011 (add 1 = two's complement representation of -5)

Masafa ya 8-bit Two's Complement:

-128 (1000 0000) to 127 (0111 1111)
