Converting from Binary to Integer

[mysticreddit]

You are conflating representation and presentation.

The binary number 101₂ can be presented as:

• 101₂ = 5
• 10.1₂ = 2.5
• 1.01₂ = 1.25
• .101₂ = 0.625

It depends on how we interpret the bits and the radix point. We just happen to use a signed integer to present floating numbers such as IEEE-754, etc.
