Syntax

f32.eq

Stack In

f32 The first value to check with.

Examples

;; Push the f32 value 3.142 onto the stack
f32.const 3.142

;; Push the f32 value 2.718 onto the stack
f32.const 2.718

;; Pop the two f32 values off the stack, check if they are the same and
;; push the result back onto the stack
f32.eq

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

;; Push the f32 value 3.142 onto the stack
f32.const 3.142

;; Push the f32 value 3.142 onto the stack
f32.const 3.142
