...?Calculus: **Numerical** **Analysis** As early as the time of Archimedes in 3rd century BCE, integral and differential studies began when Archimedes used a method of approximation in calculating bounded areas and volumes of particular solids. Since no algorithm had yet come up during such endeavor, German astronomer Johann Kepler (1571 – 1630) reformed conventions set by Archimedes and promoted new techniques of approximation. By rotating a segment of conic section about an axis, Kepler managed to determine a volume of solid and this became his chief contribution to integral calculus. A contemporary Italian priest, Bonaventura Cavalieri (1598-1647), supplicated this work with fresh concept through an...

...? **Numerical** Precision **Numerical** precision Floating point numbers Floating point numbers arethe most common way of representing real numbers in computers in recent times. The numbers are mostly represented in a scientific notation which includes a base number and an exponent. For instance, 123.46 can also be expressed as 1.23456 x 102. Floating point numbers range from 1,000,000,000,000 to 0.0000000000000001. In the expression of floating point numbers, they are expressed in a normalized manner in which the radix point is put after the non-zero digit Storage in memory Floating point numbers are stored in computer memory in 4 bytes i.e. 32 bits. Floating point numbers is composed of two components that is,...

...? **Numerical** Precision **Numerical** precision. Floating-point arithmetic is reflected as an obscure issue by alot of persons because it is universal in a computer scheme. Every language almost has a floating-point data type, meaning computers that consist from PCs to supercomputers of floating-point accelerators, compilers would oftenly be needed to compile floating-point procedures and then almost every operating system should answer to floating-point exclusions like excess. This paper discusses the aspects of floating-point computer scientist should know to avoid some petty mistakes than can rather cost him a lot. Goldberg (1991) states that discrete mathematics is what distinguishes old computers from scientific computing. He adds... in the...

Computer **Numerical** Control
Computer **Numerical** Control (CNC) popularly known as **Numerical** Control (NC) is the automatic control that is integrated into mechanical tools and equipments used in manufacturing mass products. These automated instructions are abstractly encoded into a program that is used as a language by the tools. These machines were introduced in the 1940s and their gross use was initiated in the 1950s although these did not use the modern computation language that is afforded by computer programs. However, in the modern times, the machines have been well developed so that little man power is needed. End to end designs of the components have been highly developed and the...

...HISTORY OF **NUMERICAL** CONTROL DEVELOPMENT Development and implementation of the **Numerical** Control process Introduction
**Numerical** control is the automation of operated by commands that are abstractly programmed and encoded on a medium of storage. If not automated machine tools are just controlled in a manual way by way of levers or hand wheels or automated mechanically through cams only. The United States air force is credited for the development of **numerical** control.1They saw the need of developing methods of manufacturing that are more efficient for modern aircraft. With the coming of the Second World War those components that were used for fabricating jet aircraft turned to be more complex thereby needing more machining. Most... of this...

...Mathematics 13 November **Numerical** Integral The history of integrals s back to the 17th century. The basis of integrals was formed in about 1635 by an Italian mathematician known as Cavalieri. His work was the fundamental modern step towards the branch of calculus. However, the development of integrals has had many contributions by different mathematicians. Before the development of integral calculus by Gottfried Wilheim Von Leibnz and Sir Isaac Newton, several other mathematicians had made several developments using the ideas of Archimedes of Syracuse (Elroy 63). Cavalieri was one of the pioneer proponents of the idea that quantities too small cannot be divided into halves, in a concept known as the concept of...
