Square root
The sqrt instructions, short for square root, are used to get the square root of a number.
Try it
(module (import "console" "log" (func $log (param f32))) (func $main f32.const 2 ;; load a number onto the stack f32.sqrt ;; calculate the square root call $log ;; log the result ) (start $main) ) const url = "{%wasm-url%}"; await WebAssembly.instantiateStreaming(fetch(url), { console }); Syntax
wat
;; load a number onto the stack f32.const 289 ;; get the square root of 289 f32.sqrt ;; the top item on the stack will now be 17 | Instruction | Binary opcode |
|---|---|
f32.sqrt | 0x91 |
f64.sqrt | 0x9f |
