i64.rem_u
Pops two i64 values off the stack, divides the first by the second, takes the remaining amount, and then pushes that on to the stack. This looks at the values as unsigned integers (positive values only).
$result = $first % $second

Syntax

i64.rem_u

Stack In

i64 The first value to be divided.
i64 The second value to divide by.

Stack Out

i64 The remaining amount left after dividing the first value by the second one.

Examples

;; Push the i64 values onto the stack
i64.const 10
i64.const 3

;; Get remainder from 10 by 3 seeing it as unsigned
i64.rem_u

;; The stack contains an i64 value of 1 (result = 10 % 3)

;; Push the i64 values onto the stack
i64.const 0xF23AB02CF178CD56
i64.const 42

;; Get remainder from 0xF23AB02CF178CD56 by 42 seeing it as unsigned
i64.rem_u

;; The stack contains an i64 value of 8
;; result = 17454457012904054102 % 42

;; Push the i64 values onto the stack
i64.const 0xF23AB02CF178CD56
i64.const 42

;; Get remainder from 0xF23AB02CF178CD56 by 42 seeing it as signed
i64.rem_s

;; The stack contains an i64 value of -8
;; result = -992287060805497514 % 42
