Lost data when convert float to int in php

Question

My code :

var_dump($baseprice);
$parseprice=intval($baseprice);
var_dump($parseprice);

Result :

f         


        

Answer 1

The Solution would be as below

$baseprice=1705000/1.1;

var_dump($baseprice);

$parseprice=intval(ceil($baseprice));

var_dump($parseprice);

output:

float(1550000) int(1550000)

Answer 2

Before float to integer round the value then you can convert to int

$baseprice=1705000/1.1;

var_dump($baseprice);
//Before float to integer round the value then you can convert to int
$baseprice =round($baseprice);

$parseprice=intval($baseprice);
var_dump($parseprice);

Answer 3

Problem is when caculate the float, I still dont know why they have different like bellow

$baseprice= 1705000/1.1 ; // 1550000

var_dump( decbin( $baseprice )); 
var_dump( decbin(1550000)); 

We can fix this by

$baseprice = round( $baseprice );

Answer 4

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.
