How to make number_format() not to round numbers up
(18 answers)
Closed 3 years ago.
I have this number
$sku = '2200081005966';
and I want to convert the number like this without rounding the number
$new_sku = '5.96'
I already try this number_format(substr($sku, 7, 12), 0, '', '.')
but the output that I get 5.97.
Any ideas how can I make this work?
Thank you.
Add floor() around your number_format:
$sku = '2200081005966';
echo floor(number_format(substr($sku, 7, 12), 0, '', '.')*100)/100;
Outputs:
5.96
Note: It would works well in case of positive numbers, your substr always take a positive number, that's why it would be enough.
<?php
$sku = '2200081005966';
$foo=substr($sku, 9, 12);
echo substr($foo, 0,2).".".substr($foo, 3,3);
?>
first you get the last 4 charakters of the string, then you split that part and put a dot between.

I have a variable
$amount = 621.00;
I need the 30% of the variable with output 186.30
When I calculate:
$amount2 = round($amount*30/100 , 2);
echo $amount2
gives the output of 186.3
how can I have output 186.30
number_format() should do the trick.
// english notation without thousands separator
$amount2 = number_format($amount2, 2, '.', '');
// 1234.57
You could use number_format for that:
$amount2 = number_format($amount * 30 / 100, 2);
echo $amount2;
You can use number_format
For example number_format($amount2, 2)
More details: http://php.net/manual/en/function.number-format.php
use number_format($amount2,2) at the end.
See documentation here: http://php.net/manual/en/function.number-format.php

Delete digits after two decimal points, without rounding the value

I have a value 3.9609053497942. I need value 3.9 means only one value after decimal. I have used PHP number_format and round functions but it is giving me answer 4.
You could multiply the number by 10, floor() it, and then divide it back.
echo floor($value * 10) / 10;
Try with this,
echo intval((3.9609053497942*10))/10;
or
echo floor((3.9609053497942*10))/10;
There is so many possible solutions:
echo bcadd(3.9609053497942, 0, 1);
preg_match('/\d*\.\d/', 3.9609053497942, $matches);
echo $matches[0];
why not treat it as a string, like
$x = (string)3.96;
$y = explode(".",$x);
$result = $y[0] . "." . $y[1];
Did you tried like:
number_format(3.9609053497942, 1);

PHP number_format is rounding?
I need a PHP function to convert numbers into currency format like so:
444 output 444.00
444.156 output 444.15
0 output 0.00
It should not round off the last decimal digit.
try number_format method. It will get the job done for you.
$number = 444.657;
$format_number = number_format($number, 2, '.', '');
// 444.66
Without Rounding
substr(number_format($number, 3, '.', ''), 0, -1);
//444.65

Default Number of Decimal Places to Output in PHP
basically a bit of a maths problem,
$average_ppm = $total_points_given / $totalvalue;
$average_ppm now equals 2.432608695652174, I don't want to display these numbers, I just need $average_ppm to be 2.43, so to a fixed 2 decimal points. How can I do this??
Thanks for anyones time.
Use sprintf if you want a string output, or round/floor/ceil for a numeric value:
$average_ppm = 2.432608695652174;
echo sprintf("%.2f", $average_ppm); // 2.43
$approx_average_ppm = round($average_ppm, 2);
echo $approx_average_ppm; // 2.43
echo floor($average_ppm, 2); // 2.43 , even if $average_ppm = 2.439
echo ceil($average_ppm, 2); // 2.44
You could either use sprintf, round or floor/ceil depending on how you want the numbers rounded.
Most suited for your need would be round:
$average_ppm = round($total_points_given / $totalvalue,2);
If you want to have ALWAYS 2 numbers after... you can do it with number_format:
number_format(2.43260869565217, 2); // 2.43
When you got a number like: 2.400054846 and you use round you will get 2.4
and if you want it with 2 number behind you can use number_format this will output 2.40
I would use Round:
round($average_ppm, 2);
You could use the bcmath functions if they are available where the third argument is the precision
$average_ppm = bcdiv($total_points_given, $totalvalue, 2);

Show a number to two decimal places

I need to convert numbers to have .00 after them, but only if the number is an integer, or it has just 1 number after the decimal point, like so:
1.4 = 1.40
45 = 45.00
34.77 = 34.77
What reg exp to use for this simple case?
You can also use printf or sprintf
printf("%01.2f", '34.77');
$formatted_num = sprintf("%01.2f", '34.77');
number_format($number, 2, '.', '');
Read more at PHP.net. You don't need to determine if a number is an integer or not -- as long as it's a number, it will be formatted to two decimal places.
If you'd like the thousands separator, change the last parameter to ','.
Check out PHP's built-in function number_format
You can pass it a variable and it'll format it to the correct decimal places
$number = 20;
if (is_int($number)) {
$number = number_format($number, 2, '.', '');
}
read number_format
number_format($number, 2, '.', '');
$num = 0.00638835;
$avg = sscanf($num,"%f")[0] /100;
echo sprintf("%.10f", $avg);
result 0.0000638835
