- Arbitrary-precision arithmetic
- Verified computing — collection of techniques ensuring that numerical results have a guaranteed precision
- Interval arithmetic — represent every number by two floating-point numbers guaranteed to have the unknown number between them
- See also: Interval boundary element method, Interval finite element
- Interval arithmetic — represent every number by two floating-point numbers guaranteed to have the unknown number between them

Famous quotes containing the word error:
“It is the very error of the moon,
She comes more near the earth than she was wont,
And makes men mad.”
—William Shakespeare (1564–1616)
“They have their belief, these poor Tibet people, that Providence sends down always an Incarnation of Himself into every generation. At bottom some belief in a kind of pope! At bottom still better, a belief that there is a Greatest Man; that he is discoverable; that, once discovered, we ought to treat him with an obedience which knows no bounds. This is the truth of Grand Lamaism; the “discoverability” is the only error here.”
—Thomas Carlyle (1795–1881)
“You can hardly convince a man of an error in a life-time, but must content yourself with the reflection that the progress of science is slow. If he is not convinced, his grandchildren may be. The geologists tell us that it took one hundred years to prove that fossils are organic, and one hundred and fifty more to prove that they are not to be referred to the Noachian deluge.”
—Henry David Thoreau (1817–1862)
