Remainder
The rem instructions, short for remainder, are used to calculate the remainder left over when one integer is divided by another integer, similar to the % operator in other languages. The rem instructions are only available for the integer types and not for the floating point types.
Syntax
;; load two numbers onto the stack
i32.const 10
i32.const 3
;; calculate the remainder of dividing one number by the other
i32.rem
;; the top item on the stack will now be 1 (10 % 3 = 1)
