integers

integers : The integers (from the Latin integer, literally "untouched", hence "whole": the word entire comes from the same origin, but via French) are natural numbers including 0 ( 0, 1, 2, 3, ...) and their negatives (0, −1, −2, −3, ...). They are numbers that can be written without a fractional or decimal component, and fall within the set {... −2, −1, 0, 1, 2, ...}. For example, 65, 7, and −756 are integers; 1.6 and 1½ are not integers. In other terms, integers are the numbers one can count with items such as apples or fingers, and their negatives, as well as 0. More formally, the integers are the only integral domain whose positive elements are well-ordered, and in which order is preserved by addition. In algebraic number theory, these commonly understood integers, embedded in the field of rational numbers, are referred to as rational integers to distinguish them from the more broadly defined algebraic integers. Like the natural numbers, Z is closed..   More from Wikipedia

integers : In mathematics, especially in number theory, quadratic integers are a generalization of the rational integers to quadratic fields. Important examples include the Gaussian integers and the Eisenstein integers. Though they have been studied for more than a hundred years, many open problems..   More from Wikipedia

integers : A quantum computer is any device for computation that makes direct use of distinctively quantum mechanical phenomena, such as superposition and entanglement, to perform operations on data. See also: Matter & Energy Quantum Physics Quantum Computing Physics Computers & Math Quantum Computers Hacking Information Technology In a classical (or conventional) computer, information is stored as bits; in a quantum computer, it is stored as qubits (quantum bits). The basic principle of quantum computation is that the quantum properties can be used to represent and structure data, and that quantum mechanisms can be devised and built to perform operations with this data. Although quantum computing is still in its infancy, experiments have been carried out in which quantum computational operations were executed on a very small number of qubits. Research in both theoretical and practical areas continues at a frantic pace, and many national government and military funding agencies support quantum co....   More from Science Daily

  Access full lesson containing this video at: www.yourteacher.com Students review the addition and subtraction of integers using a number line, where a positive integer represents a move to the right, and a negative integer represents a move to the left. Students learn that minus a negative can be thought of as plus a positive.

Question : what are two integers whose sum is 12 and the difference is -60? (think about what integers are.)

Answer : x + y = 12 x - y = -60 Then Solve it. 2x= -48 x = -24 y= 24+12 = 36..   More from Yahoo Answers

Question : I have a text file with integers that are separated by spaces. The integers are all on one line. How would I get these integers from this file and save them into an array?

Answer : char[] anArray; anArray = new char[20]; String txt = "C:/text.txt"; BufferedReader in = new BufferedReader(new FileReader(txt)); String instr = in.readLine(); StringTokenizer st = new StringTokenizer(instr," ",false); String newstr=""; while (st.hasMoreElements()) newstr += st.nextElement(); anArray = newstr.toCharArray(); int[] newArray = new int[20]; for(int i=0;iMore from Yahoo Answers
