convert: Wasm text instruction
The convert instructions are used for converting integer numbers to floating point numbers. There are signed and unsigned versions of this instruction.
Try it
(module (import "console" "log" (func $log (param f32))) (func $main i32.const 10 ;; push an i32 onto the stack f32.convert_i32_s ;; convert from signed i32 to f32 call $log ;; log the result ) (start $main) ) const url = "{%wasm-url%}"; await WebAssembly.instantiateStreaming(fetch(url), { console }); Syntax
wat
;; push an i32 onto the stack i32.const 10 ;; convert from signed i32 to f32 f32.convert_i32_s ;; the top item on the stack will now be the value 10 of type f32 | Instruction | Binary opcode |
