How to round up the price correctly?

Question

PHP

I import the price from the price list using phpExcel
In a loop, getting the price of each column:

$price = $objPHPExcel->getActiveSheet()->getCellByColumnAndRow(4, $i)->getValue();

Some cells with a price are not imported correctly, for example, the price has a price of 543.81 , and the library displays this way when outputting 543.8099999999999
round() also does not respond to such a price. Maybe someone faced this?

Answer 1

Alternatively, round to two decimal places:

$n = '543.8099999999999';
echo(round($n*100)/100);

Answer 2

see sprintf
