<p>
  Go 1.22 includes the first “v2” package in the standard library,
  <a href="/pkg/math/rand/v2/"><code>math/rand/v2</code></a>.

with the precision of that type argument. For example, given the function:
</p>

<pre>
func dotProduct[F ~float32|~float64](v1, v2 []F) F {
	var s F
	for i, x := range v1 {
		y := v2[i]
		s += x * y
	}
	return s
}
</pre>

<p>
the product <code>x * y</code> and the addition <code>s += x * y</code>

immediately, yielding the element type's <a href="#The_zero_value">zero value</a>
after any previously sent values have been received.
</p>

<pre>
v1 := &lt;-ch
v2 = &lt;-ch
f(&lt;-ch)
&lt;-strobe  // wait until clock pulse and discard received value
</pre>

<p>
A receive expression used in an <a href="#Assignments">assignment</a> or initialization of the special form

If a vector instruction takes a length or an index as an argument then it will be the
first argument.
For example, <code>VLEIF</code> <code>$1,</code> <code>$16,</code> <code>V2</code> will load
the value sixteen into index one of <code>V2</code>.
Care should be taken when using vector instructions to ensure that they are available at
runtime.
To use vector instructions a machine must have both the vector facility (bit 129 in the
