Less or equal

The le instructions, short for less or equal, check if a number is less than or equal to another number. If the first number is less than or equal to the second number equal 1 will be pushed on to the stack, otherwise 0 will be pushed on to the stack.

The integer types have separate less or equal instructions for signed (le_s) and unsigned (le_u) numbers.

;; load 2 numbers on to the stack
local.get $num
i32.const 2

;; check if $num is less then or equal to '2'
i32.le_u

;; if $num is less than or equal to the `2`, `1` will be pushed on to the stack,
;; otherwise `0` will be pushed on to the stack.
