I have a number (as string) like this: 1.00000
How can I reformat such numbers to only look like 1?
Thanks
Use number_format()
echo number_format('1.000000'); // prints 1
Or use intval()
echo intval('1.000000'); // prints 1
Or cast it as an integer
echo (int) '1.000000'; // prints 1
You can use the floor method for it to stay as a float
floor(1.000000)

Need to round 30.61 to 30.60, Any built-in function for PHP to do this ?
If I understand your desired output correctly, that you only want to round the second decimal point, you can round with 1 decimal presicion, then use numer_format() to ensure you get the correct number of decimals.
$num = 30.61;
echo number_format(round($num, 1), 2);
round() documentation
number_format() documentation
Live demo
you can do this
$num = 3.61;
/*round to nearest decimal place*/
$test_number = round($num,1);
/* ans :3.6
format to 2 decimal place*/
$test_number = sprintf ("%.2f", $test_number);
/* ans : 3.60 */
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 want to format numbers like following
13.20 to 13.2
13.34 to 13.34
13.00 to 13
I have tried to use a combination of str_replace() and number_format() but not able to produce required result.
Please help me, if anyone have any idea.
Thanks in advance
Try using the built-in round function:
echo round(1.23456, 2);
This will return 1.23. Of course, you have to decide how many numbers after the decimal point to keep.
number_format should work:
<?php
$number = 12.345;
echo number_format($number, 1); # Produces number with one decimal precision.
?>
EDIT:
<?php
$number = 12.30;
#Strips ZEROs and decimal point from the end
echo rtrim($number, '0.'); #Result: 12.3
?>
Or just simply, this is magic :
$number + 0
// 12.30 + 0 = 12.3
Or you can cast your number to float :
echo floatval($number);
It depends on the type of variable you're using. A string 13.20 will output 13.20 but a float 13.20 will output 13.2.
All you have to do is cast it:
echo (float) '13.20'; // Will output 13.2
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
I'm trying to output a value from xml this is what I do -
<?php
echo $responseTemp->Items->Item->CustomerReviews->AverageRating;
?>
This outputs 4.5, but when I change it to the code below it displays as 8. Why isn't it displaying as 9? Thanks.
<?php
echo $responseTemp->Items->Item->CustomerReviews->AverageRating*2;
?>
Try casting the value to a numerical value first.
$num = (double) $responseTemp->Items->Item->CustomerReviews->AverageRating;
echo $num * 2;
See Type Juggling and String Conversion to Numbers on the PHP website for more information.
If you are looking for a decimal value without doing typecasting, you have to multiply by a number with a decimal. Otherwise it will return a regular integer like the number you gave it.
Try multiplying by 2.0
echo $responseTemp->Items->Item->CustomerReviews->AverageRating*2.0;
