Two-complementary number:
DATA SHEET
Binary number:
The most significant bit is given as first, the least sig-
nificant bit as last digit.
Example:
101001
represents 41 decimal.
The first digit of positive numbers is “0”, the rest of the
number is a binary number. Negative numbers start
with “1”. In order to calculate the absolute value of the
number, calculate the complement of the remaining
digits and add “1”.
Example:
0101001
represents +41 decimal
1010111
represents
−41
decimal
Signed binary number:
The first digit represents the sign of the following
binary number (1 for negative, 0 for positive sign).
Example:
0101001
represents +41 decimal
1101001
represents
−41
decimal
