x_{1} (li; number) is congruent to x_{2} (li; number; see description for canonical/traditional/contextless default usage) modulo x_{3} (li; number); \frac(x_{1 - x} is an integer.

In order to be clear (in case of poor display), (x_{1} - x_{2})/x_{3} is an integer, possibly (but not necessarily) nonpositive. Traditionally, but not necessarily, x_{3} is a strictly positive integer (in particular, x_{3} is nonzero) and is called "(the) modulus"; if x_{3 }= 1, then x_{1} and x_{2} differ only by an integer amount - in other words, they have the same fractional part. Technically, x_{1} and x_{2} are symmetric under mutual exchange and can even be equivalent; however, in a manner morally analogous to "srana", x_{2} is canonically/traditionally either the common residue (the unique element in the space which is congruent to x_{1} mod x_{3} and which is greater than or equal to 0 and strictly less than x_{3}) or the minimal residue (denoting the common residue by c, the minimal residue is either c xor c - x_{3}, whichever is strictly less than the other in absolute value), and this may even be considered as its contextless default meaning (such as in "lo se modju"). See also: dilcu, dunli, mintu, simsa, panra, dilma (a particularly close relative and generalization of this word with slightly different focus). This word is essentially identical with dilcrmadjulu; consider this word to be its gismu equivalent. It is not the modulus operator; for that, use 2/x_{3}" with quotient x_{4} // x_{1} = x_{2} modulo x_{3}">veldilcu or vei'u. It is a specific type of terpanryziltolju'i, although both occupy the word "modulo" in English. This word does not have direct access to "integer-part" but does to "fractional-part".
