--------------------------------------------------------------
The machine epsilon
-------------------
The standard defines for each floating point representation (float, double, long double) the difference between 1 and the least value greater than 1 that is representable in the given floating point type. In IEEE754 representation this number has an exponent value of the bias, and a fraction of 1. [...]
It's been mentioned before, but what do you mean by "the bias?"
If you mean the offset added to the exponent's numerical value to
produce the encoded value, that's wrong. If you mean something
else, it would be as well to explain what you mean.
