php - Show a number to two decimal places

Solution:

Use (use if you are expecting a number in float format only, else use number_format() as an answer given by Codemwnci):

echo round(520.34345, 2);   // 520.34
echo round(520.3, 2);       // 520.3
echo round(520, 2);         // 520
Copy code

From the manual:

Description:

float round(float $val [, int $precision = 0 [, int $mode = PHP_ROUND_HALF_UP ]]);
Copy code

Returns the rounded value ofval to specifiedprecision (number of digits after the decimal point).precision can also be negative or zero (default).

Example #1round() examples

<?php
    echo round(3.4);         // 3
    echo round(3.5);         // 4
    echo round(3.6);         // 4
    echo round(3.6, 0);      // 4
    echo round(1.95583, 2);  // 1.96
    echo round(1241757, -3); // 1242000
    echo round(5.045, 2);    // 5.05
    echo round(5.055, 2);    // 5.06
?>
Copy code

Example #2 mode examples

<?php
    echo round(9.5, 0, PHP_ROUND_HALF_UP);   // 10
    echo round(9.5, 0, PHP_ROUND_HALF_DOWN); // 9
    echo round(9.5, 0, PHP_ROUND_HALF_EVEN); // 10
    echo round(9.5, 0, PHP_ROUND_HALF_ODD);  // 9

    echo round(8.5, 0, PHP_ROUND_HALF_UP);   // 9
    echo round(8.5, 0, PHP_ROUND_HALF_DOWN); // 8
    echo round(8.5, 0, PHP_ROUND_HALF_EVEN); // 8
    echo round(8.5, 0, PHP_ROUND_HALF_ODD);  // 9
?>

Solution:

Alternatively,

$padded = sprintf('%0.2f', $unpadded); // 520 -> 520.00
Copy code

Solution:

http://php.net/manual/en/function.round.php

e.g.

echo round(5.045, 2);    // 5.05

echo round(5.055, 2);    // 5.06
Copy code

Solution:

Try:

$number = 1234545454; 
echo  $english_format_number = number_format($number, 2); 
Copy code

The output will be:

1,234,545,454.00
Copy code

Solution:

Use the PHP number_format() function.

For example,

$num = 7234545423;
echo number_format($num, 2);
Copy code

The output will be:

7,234,545,423.00
Copy code

Solution:

You can use the PHPprintf orsprintf functions:

Example withsprintf:

$num = 2.12;
echo sprintf("%.3f", $num);
Copy code

You can run the same withoutecho as well. Example:sprintf("%.3f", $num);

Output:

2.120
Copy code

Alternatively, withprintf:

echo printf("%.2f", $num);
Copy code

Output:

2.124
Copy code

Solution:

Another more exotic way to solve this issue is to use with a dummy value for the $right_operand of0.

$formatted_number = bcadd($number, 0, 2);
Copy code

Solution:

useround(yourValue,decimalPoint) (php manual’s page) ornumber_format(yourValue,decimalPoint);

number_format() return value as string like this type 1,234.67. so in this case you can not use it for addition or any calculation. if you try then you have to deal with Number Format Error...

In this caseround(121222.299000000,2) will be better option. The result would be 121222.29 ...

Solution:

bcdiv($number, 1, 2) // 2 varies for digits after the decimal point
Copy code

This will display exactly two digits after the decimal point.

Advantage:

If you want to display two digits after a float value only and not for int, then use this.

Solution:

Here I get two decimals after the. (dot) using a function...

function truncate_number($number, $precision = 2) {

    // Zero causes issues, and no need to truncate
    if (0 == (int)$number) {
        return $number;
    }

    // Are we negative?
    $negative = $number / abs($number);

    // Cast the number to a positive to solve rounding
    $number = abs($number);

    // Calculate precision number for dividing / multiplying
    $precision = pow(10, $precision);

    // Run the math, re-applying the negative value to ensure
    // returns correctly negative / positive
    return floor( $number * $precision ) / $precision * $negative;
}
Copy code

Results from the above function:

echo truncate_number(2.56789, 1); // 2.5
echo truncate_number(2.56789);    // 2.56
echo truncate_number(2.56789, 3); // 2.567

echo truncate_number(-2.56789, 1); // -2.5
echo truncate_number(-2.56789);    // -2.56
echo truncate_number(-2.56789, 3); // -2.567
Copy code

New Correct Answer

Use the PHP native function bcdiv

echo bcdiv(2.56789, 1, 1);  // 2.5
echo bcdiv(2.56789, 1, 2);  // 2.56
echo bcdiv(2.56789, 1, 3);  // 2.567
echo bcdiv(-2.56789, 1, 1); // -2.5
echo bcdiv(-2.56789, 1, 2); // -2.56
echo bcdiv(-2.56789, 1, 3); // -2.567
Copy code

Solution:

$retailPrice = 5.989;
echo number_format(floor($retailPrice*100)/100,2, '.', ''); 
Copy code

It will return 5.98 without rounding the number.

Solution:

Use the PHP number_format() function.

Solution:

For conditional rounding off ie. show decimal where it's really needed otherwise whole number

123.56 => 12.56

123.00 => 123

$somenumber = 123.56;

$somenumber = round($somenumber,2);

if($somenumber == intval($somenumber))
{
    $somenumber = intval($somenumber);
}

echo $somenumber; // 123.56


$somenumber = 123.00;

$somenumber = round($somenumber,2);

if($somenumber == intval($somenumber))
{
    $somenumber = intval($somenumber);
}

echo $somenumber; // 123    
Copy code

Solution:

I make my own.

$decimals = 2;
$number = 221.12345;
$number = $number * pow(10, $decimals);
$number = intval($number);
$number = $number / pow(10, $decimals);
Copy code

Solution:

round_to_2dp is a user-defined function, and nothing can be done unless you posted the declaration of that function.

However, my guess is doing this:number_format($number, 2);

Solution:

$twoDecNum = sprintf('%0.2f', round($number, 2));
Copy code

The rounding correctly rounds the number and the sprintf forces it to 2 decimal places if it happens to to be only 1 decimal place after rounding.

Solution:

Adding to other answers, since number_format() will, by default, add thousands separator.

To remove this, do this:

$number = number_format($number, 2, ".", "");
Copy code

Solution:

$number = sprintf('%0.2f', $numbers); // 520.89898989 -> 520.89
Copy code

This will give you 2 number after decimal.

Solution:

If you want to use two decimal digits in your entire project, you can define:

bcscale(2);
Copy code

Then the following function will produce your desired result:

$myvalue = 10.165445;
echo bcadd(0, $myvalue);
// result=10.11
Copy code

But if you don't use the bcscale function, you need to write the code as follows to get your desired result.

$myvalue = 10.165445;
echo bcadd(0, $myvalue, 2);
// result=10.11
Copy code

Number without round

$double = '21.188624';

Here's another solution with strtok and str_pad:

$num = 520.00
strtok(round($num, 2), '.') . '.' . str_pad(strtok('.'), 2, '0')
Copy code

Solution:

• Choose the number of decimals
• Format commas(,)
• An option to trim trailing zeros

Once and for all!

function format_number($number,$dec=0,$trim=false){
  if($trim){
    $parts = explode(".",(round($number,$dec) * 1));
    $dec = isset($parts[1]) ? strlen($parts[1]) : 0;
  }
  $formatted = number_format($number,$dec); 
  return $formatted;
}
Copy code

Examples

echo format_number(1234.5,2,true); //returns 1,234.5
echo format_number(1234.5,2);      //returns 1,234.50
echo format_number(1234.5);        //returns 1,235
Copy code

Solution:

That's the same question I came across today and want to round a number and return float value up to a given decimal place and it must not be string (as returned from number_format) the answer is

echo sprintf('%.' . $decimalPlaces . 'f', round($number, $decimalPlaces));

Solution:

In case you usemath equation like I did you can set it like this:

{math equation="x + y" x=4.4444 y=5.0000 format="%.2f"}
