Lost data when convert float to int in php

Question

My code :

$baseprice=1705000/1.1;
var_dump($baseprice);
$parseprice=intval($baseprice);
var_dump($parseprice);

Result :

float(1550000) int(1549999)

As you can see, i lost 1 number when convert from float to int, where is it,what solution for this case for convert without lost data, Thanks.

Answer 1

You are using floating point numbers which will lose precision (see this link).

If you are handling currency use integers and work in cents, pence, pfennigs, or whatever. Convert to a currency format just before display.
