DATA SHEET
5.4. Number Formats
Binary number:
Two’s-complementary number:
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”.
The most significant bit is given as first, the least sig-
nificant bit as last digit.
Example: 101001 represents 41 decimal.
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
