5.4. Number Formats

Binary number:

The most significant bit is given as first, the least signif-

icant bit as last digit.

Example: 101001 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

Two-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, you have to calculate the complement of the

remaining digits and to add 1.

Example:

0101001 represents +41 decimal

1010111 represents

−41 decimal
