Numerical Analysis
Numerical analysis provides a variety of techniques to compute approximations to mathematical numerical values. Errors arise from a trade-off between efficiency and precision, which is limited anyway, since (using floating-point arithmetic) only some rational numbers can be represented exactly. The discrepancy between the exact mathematical value and the computed value is called the approximation error.

Famous quotes containing the words numerical and/or analysis:
“The terrible tabulation of the French statists brings every piece of whim and humor to be reducible also to exact numerical ratios. If one man in twenty thousand, or in thirty thousand, eats shoes, or marries his grandmother, then, in every twenty thousand, or thirty thousand, is found one man who eats shoes, or marries his grandmother.”
—Ralph Waldo Emerson (1803–1882)
“The spider-mind acquires a faculty of memory, and, with it, a singular skill of analysis and synthesis, taking apart and putting together in different relations the meshes of its trap. Man had in the beginning no power of analysis or synthesis approaching that of the spider, or even of the honey-bee; but he had acute sensibility to the higher forces.”
—Henry Brooks Adams (1838–1918)
