Elementwise dyadic operations (cell ranks 0 0).

Variants

Add

Sub

Mul

DivJ

J %: result is float; 0 % 0 is 0, n % 0 is signed infinity.

DivApl

APL ÷: result is float; 0 ÷ 0 is 1, n ÷ 0 is a domain error.

Min

Max

Pow

Residue

x | y: y modulo x, sign following x; 0 | y is y.

Eq

Ne

Lt

Le

Gt

Ge

Lcm

Least common multiple (J *., APL ∧); logical and on booleans.

Gcd

Greatest common divisor (J +., APL ∨); logical or on booleans.

Log

x ^. y / x ⍟ y: logarithm of y to base x; always float.

Root

x %: y: the x-th root of y; always float.

Circle

k o. y / k ○ y: the circle function selected by the integer k — the trigonometric, hyperbolic and inverse families, plus the two Pythagorean forms at 0 and 4. Always float.

Binomial

x ! y: the number of ways to choose x things from y — J’s argument order. Defined for every real pair through the gamma function.

MakeComplex

J x j. y: x + 0j1 * y. Always complex.

PolarBy

J x r. y: x * ^ 0j1 * y, i.e. polar coordinates. Always complex.
