Numbers

Use this when doing arithmetic, comparisons, aggregation, or numeric conversions.

Arithmetic operators

Operator	Description	Example	Result
+	Add	+3 4	7
-	Subtract	-10 3	7
*	Multiply	*3 4	12
/	Divide	/10 2	5
%	Modulo	%10 3	1

Comparison operators

Operator	Description	Example
==	Equal	==a b
!=	Not equal	!=a b
>	Greater than	>a b
<	Less than	<a b
>=	Greater or equal	>=a b
<=	Less or equal	<=a b

All comparisons return b.

Logic

Operator	Description	Example
&	Logical AND	&a b
|	Logical OR	|a b
!	Logical NOT	!a

Math

Function	Signature	Description	Example
abs	n > n	Absolute value	abs -5 -> 5
flr	n > n	Floor	flr 3.7 -> 3
cel	n > n	Ceiling	cel 3.2 -> 4
rou	n > n	Round to nearest integer (banker’s rounding)	rou 3.7 -> 4
rnd	> n	Random float in [0, 1). Aliases: rand, random. Read this as random, not round; for rounding use rou.	rnd -> 0.42…
rnd	n n > n	Random integer in [a, b] inclusive	rnd 1 6 -> dice

Aggregation

Function	Signature	Description	Example
sum	L n > n	Sum a list of numbers	sum [1,2,3] -> 6
avg	L n > n	Average of a list of numbers	avg [2,4,6] -> 4
min	L n > n	Minimum element of a numeric list (error if empty)	min [3,1,4,1,5] -> 1
max	L n > n	Maximum element of a numeric list (error if empty)	max [3,1,4,1,5] -> 5
min	n n > n	Minimum of two numbers	min 3 7 -> 3
max	n n > n	Maximum of two numbers	max 3 7 -> 7
median	L n > n	Median of a numeric list	median [1,2,3,4,5] -> 3
stdev	L n > n	Sample standard deviation (divides by N-1)	stdev [2,4,4,4,5,5,7,9]
variance	L n > n	Sample variance (divides by N-1)	variance [...]

Conversions

Function	Signature	Description	Example
str	_ > t	Convert to string	str 42 -> "42"
num	t > n	Parse string to number	num "42" -> 42
