               <h4>WebAssembly Data Types</h4>
<p>      
WebAssembly (as of v1.0) has only four data types.
</p>
      <ul class="list-marked">
	<li>i32 : 32 Bit Integer</li>
	<li>i64 : 64 Bit Integer</li>
	<li>f32 : 32 Bit Floating Point Number</li>
	<li>f64 : 64 Bit Floating Point Number</li>
      </ul>
