Float point numbers
0.101100100 | 000100
N.B. 1st bit is the sign bit
Find the denary representation of the exponent (RHS)
Exponent (RHS) 410
Move the decimal place to the right based on the denary representation of the exponent (i.e. 4 spaces to the left)
Mantissa (LHS) 01011.001002
Sign bit 23 22 21 20 . 2-1 2-2 2-3 2-4 2-5
0 8 4 2 1 . 0.5 0.25 0.125 0.0625 0.03125
PASITIVE 1 0 1 1 . 0 0 1 0 0
1) 0.100000000 | 000010
2) 0.010000000 | 00011
1) 010. 0000000
2) 010. 0000000
Converting Floating Point (Denary) to binary
0.625
Multiply by 2 and record the whole #
i.e.
0.625 x 2 = 1.25 1
0.25 x 2 = 0.5 0
0.5 x 2 = 1 1
And. 0.101
Convert 1/3 to binary using 5 bits for your representation and 2’s complement form.
0.3333 x 2 = 0.6667 0
0.6667 x 2 = 1.3334 1
0.3334 x 2 = 0.6668 0
0.6668 x 2 = 1.3334 1
0.0101
Converting to 2’s complement
1.1011
Hexidecimal
Analogue vs. Digital II
- A digital variable is discrete both in value and in time.
- All variables
- Analogue is measurable and digital is countable
