Problem rounding decimals

[phpretard]

Here is the number:

 

$GrandTotal = "68.835";
$Deposit = round($GrandTotal , 2) * .5;

echo $Deposit;

 

I am looking for: 68.84 but the function doesn't seem to work right.

 

Any help?

You are multiplying your result with 0.5 at the end.

 

with $Deposit = round($GrandTotal , 2); it should work right.

[phpretard]

try it ... it isn't working right

[johnny86]

<?php
$GrandTotal = "68.835";
$Deposit = round($GrandTotal , 2);
echo $Deposit;

// Result: 68.84
?>

What could I be doing wrong then?

 

// do some math
$PZTotal = "17.97";
$FCTotal = "56.97";
$CHTotal = "65.7";
$GrandTotal = $PZTotal + $FCTotal + $CHTotal;
$Deposit = round($GrandTotal , 2) * .5;

// do some math
$PZTotal = "17.97";
$FCTotal = "56.97";
$CHTotal = "65.7";
$GrandTotal = $PZTotal + $FCTotal + $CHTotal;
$Deposit = round($GrandTotal , 2) * .5; // This is wrong remove * .5 <-- that multiplys the result with 0.5
                                                       // which meand that it is divided by 2....
                                                       //SO Correct: $Deposit = round($GrandTotal , 2);

// do some math
$PZTotal = "17.97";
$FCTotal = "56.97";
$CHTotal = "65.7";
$GrandTotal = $PZTotal + $FCTotal + $CHTotal;
$Deposit = round($GrandTotal , 2) * .5; // This is wrong remove * .5 <-- that multiplys the result with 0.5
                                                       // which meand that it is divided by 2....
                                                       //SO Correct: $Deposit = round($GrandTotal , 2);

 

The deposit is half of the $GrandTotal.  Where should I do that math?

[phpretard]

$Half = $GrandTotal * .5;

$Deposit = round($Half, 2);

 

This works.  Thank you all!

You need to divide it first and then round it.

 

$Deposit = $GrandTotal * 0.5;
$Deposit = round($Deposit, 2);
