1111 (2) = 1*2^3+1*2^2+1*2^1+1*2^0 =15 (10)
111001 (2) = 1*2^5+1*2^4+1*2^3+0*2^2+0*2^1+1*2^0 = 57 (10)
101011 (2) = 1*2^5+0*2^4+1*2^3+0*2^2+1*2^1+1*2^0 = 43 (10)
11.11 (2) = 1*2^1+1*2^0+1*2^(-1)+1*2^(-2) = 3.75 (10)
1.111 (2) = 1*2^0+1*2^(-1)+1*2^(-2)+1*2^(-3) = 1.875 (10)
111.1 (2) = 1*2^2+1*2^1+1*2^0+1*2^(-1) = 7.5 (10)
111001 (2) = 1*2^5+1*2^4+1*2^3+0*2^2+0*2^1+1*2^0 = 57 (10)
101011 (2) = 1*2^5+0*2^4+1*2^3+0*2^2+1*2^1+1*2^0 = 43 (10)
11.11 (2) = 1*2^1+1*2^0+1*2^(-1)+1*2^(-2) = 3.75 (10)
1.111 (2) = 1*2^0+1*2^(-1)+1*2^(-2)+1*2^(-3) = 1.875 (10)
111.1 (2) = 1*2^2+1*2^1+1*2^0+1*2^(-1) = 7.5 (10)
