How to output whole number float in YAML?

I'm using the Symfony YAML component. If I output data from my database, numbers come up as strings so I'm converting them to the appropriate type (int or float) using filter_var.

However, outputting floats that are whole numbers like 7.0 instead outputs !!float 7. The 7.0 is parsed perfectly fine as a float in PHP, it only changes it on output.

Example code:

<?php
require 'vendor/autoload.php';
use Symfony\Component\Yaml\Yaml;

$yaml = 'test: { PHP: 7.0, MySQL: 5.5 }';
echo Yaml::dump(Yaml::parse($yaml));

Output:

test:
    PHP: !!float 7
    MySQL: 5.5

But I want:

test:
    PHP: 7.0
    MySQL: 5.5

Is there a way to do this? Can't see anything in the options.

No, there is no way to influence how a floating point value is dumped. The corresponding code from the Yaml component looks like this:

if (\is_float($value)) {
    $repr = (string) $value;
    if (is_infinite($value)) {
        $repr = str_ireplace('INF', '.Inf', $repr);
    } elseif (floor($value) == $value && $repr == $value) {
        // Preserve float data type since storing a whole number will result in integer value.
        $repr = '!!float '.$repr;
    }
} else {
    $repr = \is_string($value) ? "'$value'" : (string) $value;
}
