binary mekso operator: mod(ulus)/remainder; X1 \% X2, \,\,\, X1 (mod(X2)).

Denoted as "\%" in C++. This is a basic arithmetic operator in some programming languages. x \% y is in [0, y) for all real numbers x and y, such that/where y > 0 definitionally, and outputs the modulus/remainder of its left-hand/first input (here: x) wrt/when integer-dividing it by its right-hand/second input (here: y); in other words, let n be the greatest integer such that n y =< abs(x), then this function yields abs(x) - n y. This function can also be used in order to define the fractional-part function (define y=1). See also: "vei'e".

In notes:

x1 (li; number) is congruent to x2 (li; number; see description for canonical/traditional/contextless default usage) modulo x3 (li; number); \frac(x1 - x is an integer.
mekso quaternary operator – Pochhammer symbol: with/for input (X1, X, this word/function outputs \prodk = 0^X2 - 1 (X; by default, X4 = 1 unless explicitly defined otherwise.
mekso binary operator – quotient from integer-division: sgn(X1) sgn(X2) ((abs(X1) - (abs(X1) \% X.
binary mekso operator: form quotient space X1/X.
