show long number in format number in blade laravel

I have number like this:
2,800,000,000 billion
and I want show it like this 2.8 billion
I try this

{{rtrim($amounts,0)}}

but its show 28 billion and its not correct

how can write this in blade laravel?

>Solution :

you do it just like below

$number = 2800000000;
$formatted = number_format($number / 1000000000, 1, '.', '') . ' billion';

echo $formatted; // Output: 2.8 billion

for your specific case it could be something like this

{{number_format($amounts / 1000000000, 1, '.', '')}}
