2 3 +    // 5
10 3 %   // 1

Comparison

Operator	Mnemonic	Description
==	a b -> bool	equal
!=	a b -> bool	not equal
<	a b -> bool	less than
>	a b -> bool	greater than

\|\|	bool bool -> bool	OR
lnot	bool -> bool	NOT

Bitwise

Operator	Mnemonic	Description

^	a b -> c	XOR
<<	a b -> c	shift left
>>	a b -> c	shift right

2 3 <<    // 16
2 3 >>    // 0

2 3 ^     // 1

Memory
