Show a number to two decimal places
(25 answers)

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

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.

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

Print numeric values to two decimal places

hello i'm trying to find %. first i found the seconds
$tm=sum_the_time($d_duration);
$d_seconds='0';
list($hour,$minute,$second) = explode(':', $tm);
$d_seconds += $hour*3600;
$d_seconds += $minute*60;
$d_seconds += $second;
$total_second=$c_seconds+$p_seconds+$t_seconds+$b_seconds+$d_seconds;
$c_seconds=$c_seconds*100/$total_second;
$p_seconds=$p_seconds*100/$total_second;
$t_seconds=$t_seconds*100/$total_second;
$b_seconds=$b_seconds*100/$total_second;
$d_seconds=$d_seconds*100/$total_second;
echo $c_seconds;
the result is 10.754504504505, how would I print this code like 10.7
You can try using printf() function:
printf("%.1f", $c_seconds);
Or, number_format():
echo number_format( $c_seconds, 1 );
These two functions will round your number (will return 10.8 in your example), so, if you want to just truncate to the first decimal place (result to be equal to 10.7), you can use the following:
echo substr($c_seconds, 0, strpos($c_seconds, ".") + 2);
Actually, you can use the solutions from this question to better use number_format() and get your desired result.
echo sprintf('%0.1f', $c_seconds);
relevant docs here: http://php.net/sprintf
http://php.net/manual/en/function.number-format.php numberformat is propably what you are looking for.

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
