### Why is there more frequent overflow in normalised Floating Point

I read that overflow is more frequent when we work with normalised mantissas. Why is this? Is it because when we adopt a normalised representation, our range is smaller than in a unnormalised ...

### What is 0.1 converted to 8bit IEEE754?

0.1 via $32\text{ bit}$ is rather easy: Sign: $0_2 = 0_{10}$ Exponent: $123_{10} = 01111011_2$ Mantissa: $5033165_{10} = 100110011001100110011001101_2$ Now, how do you calculate this, if you've ...
