Equal

The eq instructions, short for equal, check if two numbers are equal. If both numbers are equal 1 will be pushed on to the stack, otherwise 0 will be pushed on to the stack.

Similarly, the eqz instructions check if a number is equal to zero, the eqz instructions are only available for the integer types and not for the floating point types.

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

;; check if $num is equal to '2'
i32.eq

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