Question

I’m using PHP’s number_format to display floats to 2 decimal places.

When the number is something like 1.898 it gets rounded up to 1.9.

How do I get it to display that as 1.90?

Update:

I have a function that ends…

return number_formant($num, 2);

The php script that calls the function prints out the number to be used by Javascript. When I do a var_dump on the number, it prints correctly with two decimal places. Looks like it’s Javascript that’s loosing the zero.

Here’s the JS code that was causing the issue…

function show_level(level) {
...
if (level > 9999)
    level_label = (level / 1000).toPrecision(3) + 'k';
else if (level > 999)
    level_label = (level / 1000).toPrecision(2) + 'k';
else
    level_label = level;

I altered the last line to get it working how I wanted..

  level_label = level.toFixed(2);

Maybe not the best solution but:

$n = 1.2345;
$n = number_format( round($n, 1), 2);
//echo 1.20
echo $n;
