n. 1 The act of truncate or shortening (in all senses) 2 (context mathematics English) The removal of the least significant digits from a decimal number 3 (context geometry English) The replacement of a solid angle by a plane (or a similar operation in other dimensions)

1. n. the property of being truncated or short [syn: shortness]

2. the replacement of an edge or solid angle (as in cutting a gemstone) by a plane (especially by a plane that is equally inclined to the adjacent faces)

3. the act of cutting short; "it is an obvious truncation of the verse"; "they were sentenced to a truncation of their limbs"

In mathematics and computer science, truncation is limiting the number of digits right of the decimal point.

Truncation is the term used for limiting the number of digits right of the decimal point by discarding the least significant ones.

Truncation may also refer to:

In statistics, truncation results in values that are limited above or below, resulting in a truncated sample. Truncation is similar to but distinct from the concept of statistical censoring. A truncated sample can be thought of as being equivalent to an underlying sample with all values outside the bounds entirely omitted, with not even a count of those omitted being kept. With statistical censoring, a note would be recorded documenting which bound (upper or lower) had been exceeded and the value of that bound. With truncated sampling, no note is recorded.
