Noun

characteristic (plural characteristics)

1. A distinguishing feature of a person or thing.
2. (mathematics) The integer part of a logarithm.
   • 1830, Solomon Pearson Miles, Thomas Sherwin, Mathematical Tables: Comprising Logarithms of Numbers, […] , page 69,

     It is evident, moreover, that as the logarithms of numbers, which are tenfold, the one of the other, do not differ except in their characteristics, it is sufficient that the tables contain the fractional parts only of the logarithms.

   • 1911, F. T. Swanwick, Elementary Trigonometry, Cambridge University Press, page 60,

     As the sine and cosine are always proper fractions their logarithms are negative, i.e. have negative characteristics. When we are given an angle, it is impossible to say, from inspection of the angle, what the characteristic of the logarithm of its sine, cosine or tangent may be; so the characteristics have to be printed with the mantissae.

   • 1961, Principles and Applications of Mathematics for Communications-Electronics, [U.S.] Department of the Army, page 69,

     Similarly, the characteristic for .003 is ?3, and the characteristic for .0003 is ?4.

3. (nautical) The distinguishing features of a navigational light on a lighthouse etc by which it can be identified (colour, pattern of flashes etc.).
4. (algebra, field theory, ring theory) For a given field or ring, a natural number that is either the smallest positive number n such that n instances of the multiplicative identity (1) summed together yield the additive identity (0) or, if no such number exists, the number 0.
   • 1962 [John Wiley & Sons], Nathan Jacobson, Lie Algebras, 1979, Dover, page 289,

     In this chapter we study the problem of classifying the finite-dimensional simple Lie algebras over an arbitrary field of characteristic 0.

   • 1992, Simeon Ivanov (translator), P. M. Gudivok, E. Ya. Pogorilyak, On Modular Representations of Finite Groups over Integral Domains, Simeon Ivanov (editor), Galois Theory, Rings, Algebraic Groups and Their Applications, American Mathematical Society, page 87,

     Let R be a Noetherian factorial ring of characteristic p which is not a field.

   • 1993, S. Warner, Topological Rings, Elsevier (North-Holland), page 424,

     Traditionally, a complete, discretely valued field of characteristic zero, the maximal ideal of whose valuation ring is generated by the prime number p, has been called a p-adic field. In our terminology, the valuation ring of a p-adic field is a Cohen ring of characteristic zero whose residue field has characteristic p, and consequently a p-adic field is simply the quotient field of such a Cohen ring.

     Genera nominum sunt sex: masculinum, ut hic Cato; femininum, ut haec musa; neutrum, ut hoc monile; commune duorum generum, ut hic et haec sacerdos: trium generum, ut hic, et haec, et hoc felix; epicoenon, quod Latine promiscuum dicitur, ut passer, aquila.

     Nouns have six genders: masculine, e.g. hic Cato 'this man Cato'; feminine, e.g. haec musa 'this muse'; neuter, e.g. hoc monile 'this necklace'; common to two genders, e.g. hic et haec sacerdos 'this priest or priestess'; of three genders, e.g. hic, et haec, et hoc felix 'this lucky man, woman or thing'; epicene, called promiscous in Latin, e.g. passer 'sparrow', aquila 'eagle'.

     Genera nominum, septem sunt. Masculinum, cui praeponitur hic: ut hic Dominus. Foemineum, cui praeponitur haec: ut haec musa. Neutrum, cui praeponuntur hoc: ut hoc templum. Commune, cui praeponuntur hic, & haec: ut hic, & haec Sacerdos. Omne, cui praeponuntur hic, haec, hoc, vel per tres varias voces inflectitur: ut hic, haec, hoc felix, bonus, bona, bonum. Dubium, quod modo masculinum, modo faemineum, apud Oratores etiam invenitur: ut hic, vel haec dies. Promiscuum, in quo sexus uterque per alterum apparet: ut hic passer, haec aquila, hic lepus.

Neuter, which you can precede with hoc, e.g. hoc templum 'this temple'. Common, which you can precede with hic and haec: hic & haec sacerdos 'this male or female priest'. Universal, which you can precede with all three of hic, haec, hoc, or which vary in three forms, e.g. hic, haec, hoc felix 'this lucky man, woman, thing', hic bonus, haec bona, hoc bonum 'this good man, good woman, good thing'. Doubtful, which in the orators can be found to be sometimes masculine, sometimes feminine, e.g. hic, vel haec dies 'this day'. Promiscuous, in which a gender appears instead of another, e.g. hic passer 'this sparrow' (always masculine), haec aquila 'this eagle' (always feminine), hic lepus 'this rabbit' (always masculine).
