Printing float up to six decimal places
<p>I have an issue in printing a float number.
I tried:</p>

<pre><code>a = 2
c = 4
print (str(c/a).format(1.6))
</code></pre>

<p>Output:</p>

<pre><code>2.0
</code></pre>

<p>Required Output:</p>

<pre><code>2.000000
</code></pre>

<p>How can I print up to 6 decimal places?</p>
