Concepts inHigh-precision division and square root
Division (mathematics)
In mathematics, especially in elementary arithmetic, division (÷) is an arithmetic operation. Specifically, if b times c equals a, written: where b is not zero, then a divided by b equals c, written: a ÷ b = c For instance, 6 ÷ 3 = 2 since 6 = 3 * 2 In the expression a ÷ b = c, a is called the dividend, b the divisor and c the quotient. Conceptually, division describes two distinct but related settings. Partitioning involves taking a set of size a and forming b groups that are equal in size.

Square root
In mathematics, a square root of a number a is a number y such that y = a, or, in other words, a number y whose square (the result of multiplying the number by itself, or y × y) is a. For example, 4 is a square root of 16 because 4 = 16. Every non-negative real number a has a unique non-negative square root, called the principal square root, which is denoted by, where ¿ is called radical sign. For example, the principal square root of 9 is 3, denoted, because {{{1}}} and 3 is non-negative.

Floating point
In computing, floating point describes a method of representing real numbers in a way that can support a wide range of values. Numbers are, in general, represented approximately to a fixed number of significant digits and scaled using an exponent. The base for the scaling is normally 2, 10 or 16.

Bit
A bit (a contraction of binary digit) is the basic capacity of information in computing and telecommunications; a bit represents either 1 or 0 (one or zero) only. The representation may be implemented, in a variety of systems, by means of a two state device. In computing, a bit can be defined as a variable or computed quantity that can have only two possible values. These two values are often interpreted as binary digits and are usually denoted by the numerical digits 0 and 1.

Personal computer hardware
Personal computer hardware are the component devices that are the building blocks of personal computers. These are typically installed into a computer case, or attached to it by a cable or through a port. In the latter case, they are also referred to as peripherals.
