wrap instruction, is used to convert numbers of type
i64 to type
i32. If the number is larger than what an
i32 can hold this operation will wrap, resulting in a different number.
One can think of wrap either as reducing the value mod 232, or as discarding the high 32 bits to produce a value containing just the low 32 bits.
;; push an i64 onto the stack i64.const 10 ;; wrap from i64 to i32 i32.wrap_i64 ;; the top item on the stack will now be the value 10 of type `i32`
