if ($first === $second) {...}

Syntax

f64.eq

Stack In

f64 The first value to check with.
f64 The second value to check against.

Examples

;; Push the f64 value 3.142 onto the stack
f64.const 3.142

;; Push the f64 value 2.718 onto the stack
f64.const 2.718

;; Pop the two f64 values off the stack, check if they are the same and
;; push the result back onto the stack
f64.eq

;; The stack contains an i32 value of 0 (not the same)

;; Push the f64 value 3.142 onto the stack
f64.const 3.142

;; Push the f64 value 3.142 onto the stack
f64.const 3.142

;; Pop the two f64 values off the stack, check if they are the same and
;; push the result back onto the stack
