comment Need help for a beginner to floating-point arithmetic
@hardmath as you found it, machine epsilon is 0.25. so does this imply that $m_3=0$. Then,all the possible values the mantissa can take:0.110,0.100,0.010,0000?

comment smallest poisitive integer does not belong in floating point system F
to not represent some integers, we need $\beta^{e-t}$ to be larger than 1. in this case the smallest e is t+1. so we have $x=m.\beta$
