Binary to Decimal Conversion
To convert a binary numbers Into decimal number, following are the steps:
Step 1: Write the given binary Number
Step 2: Write the binary weightage below each number
Step 3: Cancel the weightage, which is placed below zero because any number multiplied by zero is zero.
Step 4: Add the remaining numbers.
Examples Of Binary to Decimal Conversion
1) Convert (110011)2 into decimal
1 1 0 0 1 1
= 25 + 24 + 23 + 22 + 21 + 20
= 32 + 16 + `\cancel(8)` + `\cancel(4)` + 2 + 1
=(51)10
∴ (110011)2 = (51)10
2) If (100001)2 = (x)10 find X
1 0 0 0 0 1
32 + `\cancel(16)`+ `\cancel(8)`+ `\cancel(4)`+ `\cancel(2)`+ 1
X = 33
∴(100001)2 = (33)10
Fractional binary numbers:
To convert the mixed binary numbers containing integers and fractions, we can follow the same steps
1) Convert (1100 . 1011)2 into decimal
(1100 . 1011)2 = (1 x 23) + ( 1 x 22) + (0 x 21) + (0 x 20) + (1 x 2-1) + (0 x 2-2) + (1 x 2-3) + (1 x 2-4)
= 8 + 4 + 0 + 0 + 0.5 + 0 + 0.125 + 0.0625
= (12.6875) 10.
