A floating point is a digital representation of a number used in computer operations, but it doesn’t exist on number lines or math books. It generates enough random numbers to power complex data interactions and is popular with hardware and software manufacturers. However, financial experts find it unstable. The IEEE standard is the basis for many programming languages and security protocols.
Despite its concrete-sounding name, a floating point is something that technically doesn’t exist. People cannot prove its existence, yet it is used millions of times a day in computer operations. How and why this happens is fascinating to many people.
A floating point is, at its heart, a number. In technical terms, it is a digital representation of a number, an approximation of an actual number. However, it doesn’t exist on number lines or the pages of math books. The moving points form the basis of computer calculations.
Usually, these numbers are a combination of whole numbers and their various multipliers. In computer terms, the number two is usually the basis in such an operation. Using such a base and various exponents, the computer will perform operations by the millions. The vast majority of these operations are powered by floating point numbers.
The idea behind floating point numbers is to generate enough random numbers to power the often complex data interactions that make up the most basic and most complicated functions of a computer. Displaying the date and time, for example, might require a few or perhaps a handful of calculations, depending on a number of variables. Displaying options and results for graphics-intensive software programs, however, may require calculations to be numbered in the millions.
A sometimes interesting byproduct of these calculations is that numbers that would be equal on a number line or in number equations can coexist. For example, both 0.01 x 10(1) and 1.00 x 10(-1) equal 0.1 if we write them as parts of an equation, but floating point calculations allow for both simply because they are written differently. Equations, which tend to want to make things as simple as possible, are not floating point calculations and vice versa.
One problem with such calculations that is quite unpopular with financial software vendors, whose users demand exact calculations down to the smallest sides of the decimal point, is that the numbers are not defined at all. It is fine to state the time and date using this type of calculation, but determining the net worth of a multinational corporation for a given fiscal year requires much more definite numerical accounting than the inherent random result provided by a floating point calculation. The words themselves suggest that the numbers are far from stable, and this kind of insecurity makes financial experts uneasy.
However, floating point arithmetic is popular with hardware and software manufacturers around the world. One of the most popular standards today is the IEEE standard, an international set of guidelines for structuring and analyzing these calculations. This standard forms the basis of many programming languages and security protocols.
