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)
“Analysis as an instrument of enlightenment and civilization is good, in so far as it shatters absurd convictions, acts as a solvent upon natural prejudices, and undermines authority; good, in other words, in that it sets free, refines, humanizes, makes slaves ripe for freedom. But it is bad, very bad, in so far as it stands in the way of action, cannot shape the vital forces, maims life at its roots. Analysis can be a very unappetizing affair, as much so as death.”
—Thomas Mann (1875–1955)
