Is $x$ in the working range [3,2]?


Consider $ x$ = $ (0.1001)_b$ and $ F$ [3,2]. ($ F$ [3,2] is the set of all floating point numbers with 3 digits in the mantissa and 2 digits in the exponent.)

The question is $ x$ in the working range [3,2]?

I am quite confused does $ F$ [3,2] mean $ (0.111)_b$ x $ 2^{11}$ = $ (111)_b$ ?
