In JVM float value stores in binary system. But how it exactly stored? In example.
int value = Math.pow(10,8) + 1;
float f = value;
int back = (int)f;
back value is equal to 10^8. Where is 1

You should read IEEE 758 https://en.wikipedia.org/wiki/IEEE_floating_point – Aubin Feb 24 '17 at 12:01

Do study the 3 links above. As near as dammit is to swearing, a `float` can only store 7 significant figures of data. Hence `1` is not significant in a number with magnitude 10e8. As for how it's stored, study the first link. – Bathsheba Feb 24 '17 at 12:10
