Interval arithmetic

（重定向自Interval analysis）

Tolerance function (turquoise) and interval-valued approximation (red)

Body Mass Index for a person 1.80 m tall in relation to body weight m (in kilograms)

Body mass index for different weights in relation to height L (in metres)

Interval arithmetic, interval mathematics, interval analysis, or interval computation, is a method developed by mathematicians since the 1950s and 1960s, as an approach to putting bounds on rounding errors and measurement errors in mathematical computation and thus developing numerical methods that yield reliable results. Very simply put, it represents each value as a range of possibilities. For example, instead of estimating the height of someone using standard arithmetic as 2.0 metres, using interval arithmetic we might be certain that that person is somewhere between 1.97 and 2.03 metres.
