vei'u VUhU1 experimental cmavo

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".

On grammatical class:

n-ary mathematical operator: divided by; division operator; [(((a / b) / c) / ...)].
n-ary mathematical operator: times; multiplication operator; [(((a * b) * c) * ...)].
n-ary mathematical operator: plus; addition operator; [(((a + b) + c) + ...)].
n-ary mathematical operator: minus; subtraction operator; [(((a - b) - c) - ...)].
vei'e (exp!)
mekso binary operator – quotient from integer-division: sgn(X1) sgn(X2) ((abs(X1) - (abs(X1) \% X.
vei'u (exp!)
binary mekso operator: mod(ulus)/remainder; X1 \% X2, \,\,\, X1 (mod(X2)).

In notes:

ma'oi (exp!)
selma'o quote; quotes a word (a cmavo) and uses it to name a selma'o.
ma'oi'e (exp!)
Like "ma'oi" but outputs the officially-designated/canonical sub-selma'o (if any) to which the immediately following and quoted word (cmavo) belongs, otherwise outputting the whole relevant selma'o in fashion equivalent to "ma'oi".
