-010110补码

To determine the 2's complement of -0.10110, we need to follow these steps:

1. Convert the number to its positive binary representation. -0.10110 in binary: 1.10110

2. Invert all the bits (1s become 0s, and 0s become 1s). Inverted binary: 0.01001

3. Add 1 to the inverted binary representation. 0.01001 + 1 = 0.01010

Therefore, the 2's complement of -0.10110 is 0.01010.
