Set a numeric attribute associated with the formatter. An example of a numeric attribute is the number of integer digits the formatter will produce.
formatterNumberFormatter object.
attributeAttribute specifier - one of the numeric attribute constants.
valueThe attribute value.
Beispiel #1 numfmt_set_attribute() example
<?php
$fmt = numfmt_create( 'de_DE', NumberFormatter::DECIMAL );
echo "Digits: ".numfmt_get_attribute($fmt, NumberFormatter::MAX_FRACTION_DIGITS)."\n";
echo numfmt_format($fmt, 1234567.891234567890000)."\n";
numfmt_set_attribute($fmt, NumberFormatter::MAX_FRACTION_DIGITS, 2);
echo "Digits: ".numfmt_get_attribute($fmt, NumberFormatter::MAX_FRACTION_DIGITS)."\n";
echo numfmt_format($fmt, 1234567.891234567890000)."\n";
?>Beispiel #2 OO example
<?php
$fmt = new NumberFormatter( 'de_DE', NumberFormatter::DECIMAL );
echo "Digits: ".$fmt->getAttribute(NumberFormatter::MAX_FRACTION_DIGITS)."\n";
echo $fmt->format(1234567.891234567890000)."\n";
$fmt->setAttribute(NumberFormatter::MAX_FRACTION_DIGITS, 2);
echo "Digits: ".$fmt->getAttribute(NumberFormatter::MAX_FRACTION_DIGITS)."\n";
echo $fmt->format(1234567.891234567890000)."\n";
?>Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
Digits: 3 1.234.567,891 Digits: 2 1.234.567,89
Beispiel #3 Using NumberFormatter::ROUNDING_MODE to truncate values
By default, NumberFormatter rounds values. Using
NumberFormatter::ROUND_DOWN as the
NumberFormatter::ROUNDING_MODE truncates
the value to the specified number of fraction digits without rounding.
<?php
$fmt = new NumberFormatter('en_US', NumberFormatter::DECIMAL);
$fmt->setAttribute(NumberFormatter::FRACTION_DIGITS, 2);
echo "Default rounding mode:\n";
echo $fmt->format(3.789), "\n"; // 3.79 (rounded up)
echo $fmt->format(3.781), "\n"; // 3.78 (rounded down)
$fmt->setAttribute(NumberFormatter::ROUNDING_MODE, NumberFormatter::ROUND_DOWN);
echo "\nWith ROUND_DOWN (truncate):\n";
echo $fmt->format(3.789), "\n"; // 3.78 (truncated)
echo $fmt->format(3.781), "\n"; // 3.78 (truncated)
?>Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
Default rounding mode: 3.79 3.78 With ROUND_DOWN (truncate): 3.78 3.78
