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"; ?>
