### Example of conversion to decimal of a binary signed fraction

Let's convert to decimal the following signed binary fraction: 1.01101.

1.01101 = -1 + 0×2^{-1} + 1×2^{-2} + 1×2^{-3}
+ 0×2^{-4} + 1×2^{-5} = -0.59375.

Another way to convert the number is to find its 2's complement: we invert all the bits, and add 1:

0.10010 + 1 = 0.10011. Then 1.01101 = -(1×2^{-1} + 1×2^{-4} + 1×2^{-5}) = -0.59375
