Example 3.1 Convert the binary number (110.11)2 to decimal: (110.11)2 = 6.75
Example 2.3 Convert the hexadecimal number (1A.23)16 to decimal : 1A.23 = 26.137
Convert from decimal to any base.
We can convert a decimal number to its equivalent in any base. We need two procedures,
one for the integral part and one for the fractional part.
Example 2.4
What is the binary equivalent of (24C)16?
Solution
Each hexadecimal digit is converted to 4-bit patterns: 2 → 0010, 4 → 0100, and C → 1100.
The result is (001001001100)2.
Binary–octal conversion
Example 2.5
What is the binary equivalent of for (24)8?
Solution
Write each octal digit as its equivalent bit pattern to get (010100)2.
Octal–hexadecimal conversion

• In the binary graphic method of representing an image in a computer,
each pixel is assigned a bit patterns.
(1.0101)x2-4 =>(1.M)x2e
Excess -> S E M
Dấu S = 0/1
Độ lớn M =0101
Bias = 127 = 28-1 -1
e = -4
Giá trị mũ E= e + Bias= 123
