In some cases, three-way comparison can be simulated by subtracting A and B and examining the sign of the result, exploiting special instructions for examining the sign of a number. However, this requires the type of A and B to have a well-defined difference.
When it is desired to associate a numeric value with the result of a comparison between two data items, say a and b, the usual convention is to assign −1 if a < b, 0 if a = b and 1 if a > b. For example, the C function strcmp performs a three-way comparison and returns −1, 0, or 1 according to this convention, and qsort expects the ...
In statistics, the likelihood-ratio test is a hypothesis test that involves comparing the goodness of fit of two competing statistical models, typically one found by maximization over the entire parameter space and another found after imposing some constraint, based on the ratio of their likelihoods.
The relational algebra uses set union, set difference, and Cartesian product from set theory, and adds additional constraints to these operators to create new ones.. For set union and set difference, the two relations involved must be union-compatible—that is, the two relations must have the same set of attributes.
The primary use of comparison in literature is with the simile, a figure of speech that directly compares two things. [12] [13] Similes are a form of metaphor that explicitly use connecting words (such as like, as, so, than, or various verbs such as resemble) [12] though these specific words are not always necessary.

The "false equivalence" is the comparison between things differing by many orders of magnitude: [3] Deepwater Horizon spilled 210 million US gal (790 million L) of oil; [4] one's neighbor might spill perhaps 1 US pt (0.47 L).
