Since we're off in the weeds, here's how you convert 1100110.11 to base 10.

Shift left by 2, which is equivalent to multiplying by 4:

1100110.11 -> 110011011

Convert the (now point-less) value to decimal:

110011011b -> 411

Divide by the factor of 4 that was introduced above:

411/4 -> 102.75

Problem solved. You'd think people had never manipulated fixed-point numbers before.
