Numerical operators

Learn how to use and combine numerical operators in APL.

Numerical operators

The types int, long, and real represent numerical types. The following operators can be used between pairs of these types:

Operator	Description	Example
+	Add	3.19 + 3.19, ago(10m) + 10m
-	Subtract	0.26 - 0.23
*	Multiply	1s * 5, 5 * 5
/	Divide	10m / 1s, 4 / 2
%	Modulo	10 % 3, 5 % 2
<	Less	1 < 2, 1 <= 1
>	Greater	0.23 > 0.22, 10min > 1sec, now() > ago(1d)
==	Equals	3 == 3
!=	Not equals	2 != 1
<=	Less or Equal	5 <= 6
>=	Greater or Equal	7 >= 6
in	Equals to one of the elements	"abc" in ("123", "345", "abc")
!in	Not equals to any of the elements	"bca" !in ("123", "345", "abc")
