Round of into two decimal places

[newphpcoder]

Hi..

I encountered problem in rounding of numbers into two decimal places.

here is my sample code:

if($W4_STATUS == 1 AND $DEPENDENTS == 0 AND $TotEarn >= 7917 AND $TotEarn <= 12500) {
   $TAX = ($TotEarn - 7917);
   $TAX = (937.50 + ($TAX * .25));
   $TAX = number_format($TAX, 2, '.', '');
} 

for example from this:

 $TAX = ($TotEarn - 7917);
  $TAX = (937.50 + ($TAX * .25)); 

the output is: 1417.615

using this:

$TAX = number_format($TAX, 2, '.', ''); 

the output was : 1417.61

but it should be : 1417.62

Thank you

$TAX=round($TAX,2,PHP_ROUND_HALF_UP);

I tried some testing:
$TAX = ($TotEarn - 7917); // 1920.46
$TAX = ($TAX * . 25); // 480.115

$TAX = round($TAX, 2) // 480.11

but when I tried this:

$TAX = (480.115);
$TAX = round($TAX , 2); // 480.12

I notice that if the variable is = actual numeric it works but if it is came from variable it did not work

I really don't know what to do

Thank you

$TAX=round($TAX,2,PHP_ROUND_HALF_UP);

or

$TAX=round($TAX,2,PHP_ROUND_HALF_DOWN);

depending on which way you want it to go.

I resolve my problem in round off into two decimal places by this code:

$TAX = 0.00; 

if($W4_STATUS == 1 AND $DEPENDENTS == 0 AND $TotEarn >= 2083 AND $TotEarn <= 2500) { 
  $TAX = ($TotEarn - 2083); 
  $TAX = ($TAX * .05); 
} 
elseif($W4_STATUS == 2 AND $DEPENDENTS == 0 AND $TotEarn >= 2083 AND $TotEarn <= 2500) { 
  $TAX = ($TotEarn - 2083); 
  $TAX = ($TAX * .05); 
} 

   ... 
            
elseif($W4_STATUS == 2 AND $DEPENDENTS == 4 AND $TotEarn >= 16667 AND $TotEarn <= 27083) { 
   $TAX = ($TotEarn - 16667); 
   $TAX = (2083.33 + ($TAX * .30)); 
} 
elseif($W4_STATUS == 1 AND $DEPENDENTS == 4 AND $TotEarn >= 27083 AND $TotEarn <= 50000) { 
   $TAX = (5208.33); 
} 
elseif($W4_STATUS == 2 AND $DEPENDENTS == 4 AND $TotEarn >= 27083 AND $TotEarn <= 50000) { 
    $TAX = (5208.33);  
} 
else{ 
}   

$TAX .= 0.00001; 
$TAX = round($TAX, 2); 
$TAX_Ded = number_format($TAX, 2, '.', '');

Thank you
