Definition

In calculus, error refers to the difference between an actual value or result and an estimated or approximated value or result.

Related terms

Absolute error: Absolute error measures how far off an estimated value is from an actual value without considering direction.

Relative error: Relative error compares absolute error to the magnitude of the actual value, giving us a sense of proportionality.

Percentage error: Percentage error expresses relative error as a percentage, making it easier to compare errors across different situations.
