# Numerical Methods ## Types and Sources of Errors

When we want to formulate a problem and want to implement it on computer then various errors occur at various stages. The various types and sources of errors are discussed in the following article. Numerical analysis deals with developing methods, called numerical methods, to approximate a solution of a given Mathematical problem.  The approximate solution … ## Various Computational Techniques | Types of Numerical Methods

A numerical method is a complete and definite set of procedures for the solution of a problem, together with computable error estimates. Various computational techniques are used to find the solution of a problem. The study and implementation of such methods is the field of numerical analysis or numerical methods. In this article different methods … ## Number Representation, Significant Digits, Precision, Accuracy and Errors

Numerical calculations obviously involve the operation (i.e., addition, subtraction, multiplication, etc.) of numbers. Numbers can be integers (e.g., 5,10, -16 etc.), fractions (e.g., -5/6, etc.), or an infinite string of digits (e.g., π=3.1415926535…). In numerical analysis we deal with numerical values and calculations. There are several concepts that must be considered Number representation Significant digits … ## Common Ideas and Concepts of Computational Methods

Computational method is the study of algorithms that use numerical approximation for the problems of mathematical analysis. Some common ideas and concepts of computational methods are explained in this article. Computational Methods Numerical mathematics has been used for centuries in one form or another within many areas of science and industry but modern scientific computing using electronic computers … ## Introduction to Numerical Methods

In introduction to numerical methods, the definition, need and applications of Numerical methods are explained. The word “Numerical Method” is synonymous to “Numerical Analysis”, “Computational Methods”. What is Numerical Method? In reality “Solving a math problem” generally involves finding an answer rather than exact answer. Numerical analysis is the study of algorithms that use numerical approximation for the problems of mathematical analysis. A …
