In C++ they typically consume less space than the related double but store more information than a simple int.
One approximation for doing a certain mathematical operation developed while using this representation involves the hexadecimal magic constant 5f3759df and is used to calculate a "fast inverse square root" if the input is represented in this format. De-normalized numbers are used to resolve arithmetic underflows that occur when using this representation, while an exception named after this representation is often thrown when dividing by zero. The current standard regarding the implementation of these entities is the (*) IEEE 754-2008 standard, which specifies the amount of precision they have. In C++ they typically consume less space than the related double but store more information than a simple int. For 10 points, name this common way of representing numbers using significant digits and an exponent, which are not fixed point numbers.
