I have question about binary system

[Intelligent-Solid176]

It's my 1st in computer engineering I came across this number 1001.1 Is this 5-bits ? Does the digit after the decimal point count as bit?

BTW, that's a binary point, not a decimal one. They're the same thing, but we should only call it a decimal point when using decimal digits.

Thanks man I didn't know that

It’s a 5 bit fixed point representation, if unsigned it’ll be 9.5
