IEEE-754 Float Analyzer — frequently asked questions
The standard format most programming languages and hardware use to represent floating-point (decimal) numbers in binary.
The stored exponent has 127 added to it (for single precision) so it can represent both positive and negative exponents using only unsigned bits.
