regex numbers like 1.1k : <p>in regex <code>\d+</code> match all numbers, but it doesn't match numbers like <code>1k</code> or <code>1.4k</code> how should I make a regex to count that numbers too?</p>

<p>What i want:</p>

<p>VALID:</p>

<ul>
<li>1.1K</li>
<li>1.2K</li>
<li>1.0K</li>
<li>1K</li>
</ul>

<p>INVALID:</p>

<ul>
<li>1.1</li>
</ul>

<p>I am new to regex and I don't know how to start</p>
