How to set minimum decimal digits but not maximum decimal digits. I tried with number_format but the results were unexpected.
<?php
echo number_format("1000000", 2) . "<br>";
echo number_format("1000000.6", 2) . "<br>";
echo number_format("1000000.63", 2) . "<br>";
echo number_format("1000000.68464", 2) . "<br>";
?>
Result:
1,000,000.00
1,000,000.60
1,000,000.63
1,000,000.68
Expected Result:
1,000,000.00
1,000,000.60
1,000,000.63
1,000,000.68464
How do I do this?
There’s a more advanced class called NumberFormatter which is part of the intl extension that supports both minimum and maximum, and you can just set the latter to a high number to achieve your expected results.
$f = new NumberFormatter('en-US', NumberFormatter::DECIMAL);
$f->setAttribute(NumberFormatter::MIN_FRACTION_DIGITS, 2);
$f->setAttribute(NumberFormatter::MAX_FRACTION_DIGITS, 999);
echo $f->format("1000000") . PHP_EOL;
echo $f->format("1000000.6") . PHP_EOL;
echo $f->format("1000000.63") . PHP_EOL;
echo $f->format("1000000.68464") . PHP_EOL;
Output:
1,000,000.00
1,000,000.60
1,000,000.63
1,000,000.68464
