I have the number 1.5020370483398E-5 but I want to show it as 0.00001502037. How can I convert 1.5020370483398E-5 to that number? Regular rounding functions do not work and instead just output 0.
You can use number_format()
https://www.php.net/manual/en/function.number-format.php
Here is an example on your case :
$test = 1.5020370483398E-5;
// Output : 0.00001502037
echo number_format($test, 11);

I am trying to create an ecommerce store and our prices need to fluctuate with the exchange rate for different countries so I'm dealing with a lot of decimal places.
What I want to do is round the original price to the nearest full number (as in they can keep the change). But then I want to format that as a currency with two decimal places.
<?php
$number = 12345.6789;
echo $number; // outputs '12345.6789'
$number = number_format($number,0);
echo $number; // outputs '12,346'
$number = number_format($number,2);
echo $number; // outputs '12.00'
?>
After formatting to no decimal places it starts reading the ',' as the decimal separator instead of the thousands separator and formats that for two decimal places.
It also gives the following error:
A non well formed numeric value encountered in C:\wamp64\www\Lifting365\test.php on line 6
How can I achieve what I am looking for?
As specified in the documentation, number_format returns a string value, you can't reuse it as a number.
Use the function round() to round your number, if you want to round it to the direct upper integer use ceil() instead.
number_format(round(12345.6789), 2);
// apply intval to get the low integer value (for change purposes)
$number = 12345.6789;
echo $number; // outputs '12345.6789'
echo intval($number)."<br/>"; // outputs '12345'
echo number_format(intval($number),0,'.','.'); // outputs '12.345'
echo number_format(intval($number),0,'.',','); // outputs '12,345'
Use round function and then number_format.
// returns 12,346.00
number_format(round(12345.6789), 2);
The function number_format accepts 4 parameters. Per default a point will be used as decimal seperator and comma as thousands seperator (12345.6789 become 12,346 after your first call; as excepted). It's not explicitly documented but number_format also rounds.
http://php.net/manual/de/function.number-format.php
string number_format ( float $number , int $decimals = 0 , string $dec_point = "." , string $thousands_sep = "," )
You are getting an error because you reuse the same variable $number. After your first call to number_format you dont have a float value anymore.
<?php
$number = 12345.6789;
echo $number."<br>"; // outputs 12345.6789
echo number_format($number,0)."<br>"; // outputs 12,346
echo number_format($number,2)."<br>"; // outputs 12,345.68
?>
If you are not sure what is in your variable you can apply floatval to it.
echo number_format(floatval($number),2);
The PHP function that you're looking for is money_format() http://php.net/manual/en/function.money-format.php have a good read through the manual page (including the comments)
I have looked for a way to do this and have not found it.
I have values read from MySQL: 100.00, 85.50, 97.00, 71.33
I want them to display as: 100, 85.5, 97, 71.33
I see number_format() that specifies FIXED decimal places, but I need a sort of 'significant digits format'
use (float)$number;
$a = '100.00';
$b = 73.50;
$c = 71.33;
echo (float)$a; // 100
echo (float)$b; // 73.5
echo (float)$c; // 71.33
you need to use floatval function to get your required output. just check below code.
var_dump(floatval('100.00'));
var_dump(floatval('85.50'));
var_dump(floatval('71.33'));
I have a code where I got some numbers like this:
92.682926829268
I'd like to cut them like this:
92.68
This is my code:
<td><?php if (($row['TotalMatch']) > 10){ echo ($row['OK_05'] / $row['TotalMatch']) * 100; } ?></td>
I tried with floor and round but I get that example I showed at the beginning of post ( 92.682926829268 instead of 92.68 )
Thanks for your attention
Regards!
EDIT Could you give me an example with my code? Thanks
Use sprintf() to format the number.
echo sprintf("%.2f", 92.682926829268);
Example:
https://3v4l.org/U87T9
The expression you're trying to format is this:
($row['OK_05'] / $row['TotalMatch']) * 100
So whichever function you decide to use needs to go around that expression.
As to which function to use, you need to select one that returns a string, not a float.
If you use round, and your expression returns a float that rounds to a number with two zeros after the decimal point, the trailing zeros will not be displayed in the result. For example, echo round(92.0006829268, 2) will display 92, not 92.00. So don't use round if you need to be sure that two decimal places are always displayed. round is a math function, not a formatting function.
floor is really not useful at all here, as it returns a number with no decimal places.
A simple way is to use sprintf as shown in some of the other answers.
echo sprintf("%.2f", ($row['OK_05'] / $row['TotalMatch']) * 100);
The first argument to sprintf is "%.2f", which is a format string indicating that the second argument should be displayed as a float with two decimal places. The second argument is your expression.
Using bcdiv as suggested in the other answer will also work, but it works a little differently that sprintf and will produce a slightly different result in some cases.
sprintf will round to the number of decimal places specified, so for example
echo sprintf("%.2f", 926.89 / 10); // outputs 92.69
and bcdiv will truncate instead, so
echo bcdiv(926.89, 10, 2); // outputs 92.68
Whichever one of those works for you, do that.
You can use the round function
$var = 92.682926829268;
$var = round($var, 2)
Or use sprintf (%.2f cuts the number)
$var = sprintf("%.2f", $var);
Try using sprintf like below:
<?php
$mynumber = 98.343434;
echo sprintf('%.2f', $mynumber); // this will output 98.34
You could use bcdiv()
bcdiv($row['OK_05'], ($row['TotalMatch'] * 100), 2);
I wanted to calculate the percentage using PHP. I tried the code given below but its gives me the return value in float. i don't know much in PHP so please fix this code.
current OUTPUT
66.666666666667%
Expected OUTPUT
66.66%
<?php
$up=4;
$down:2;
echo (($ups/($ups+$downs))*100).'%';
?>
Use number_format() to specify your decimals and separator.
<?php
$up=4;
$down:2;
$num = (($ups/($ups+$downs))*100).'%';
$formatted_num = number_format($num, 2, '.', '');
echo $formatted_num;
?>
You can do like this :
echo round(66.666666666667, 2); >> 66.66
I am getting the following output correctly:
<?php echo number_format("12312.312","1"); // Correct Output 12312.3 ?>
but in the following case
<?php echo number_format("12312","1"); // Getting output 12312.0 but requires only 12312 ?>
So basically, I want to control my output i.e. it should add decimal place only if my decimal digit is greater than 0.
The second parameter for number_format() takes the number of decimals - so your example is the the expected result. Maybe you are intereseted in the round() function which allows to round to a certain precision?
You can try something like this
<?php
$number = 12312;
echo is_int($number) ? $number : number_format($number,"1");
?>
If you don't want the extra decimal place, use <?php echo number_format(12312, 0);?>
The "0" represents 0 decimal places
simple casting it to float, usign (float), works.
e.g.
$num_1 = (float)1.0;
$num_2 = (float)1.1;
echo $num_1;
echo $num_2;
output:
1
1.1
