php: number format is not working

Question

I need to output a $result to two places I have tried

echo "<td>" .number_format($result,2). "</td>\n";

which results in a long string of decimals. And I have also tried "%u.1" which simply prints a ".1" literally after every number.

How do I simply output a numeric result to 1 decimal place?

You may try as :

echo "<td>" .number_format((float)$result, 1). "</td>\n";
