Binary floating point to decimal conversion quiz

Answer the following binary floating point (mantissa and exponent parts) to decimal conversion questions.
The mantissa will be represented by 6 bits and the exponent by 4 bits in the form [0.mantissa] [exponent].

Q1

  

Example

Mantissa
  -1 .   1/2   1/4   1/8  1/16  1/32  1/64
0 . 0 1 1 0 1 0
Exponent
  -8   4   2   1
0 0 1 1

= (1/4 + 1/8 + 1/32) * 2^3
= 0.40625 * 8
= 3.25
Note: the exponent tells you how many places the decimal point will 'float'.
