Print numeric values to two decimal places

Closed 11 months ago.
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.

I need split by gap like when we write count numbers we will give gap for every 3 integer.
echo chunk_split(1000255869,3," ");
I got output like: 100 025 586 9
But I need output like: 1,000,255,869
How to reverse that one?
Try this,
<?php
$a = 1000255869;
echo $a;//output - 1000255869
$a = number_format($a);
echo $a;//output - 1,000,255,869
?>
if you want to do a number format, you should do it with number_format.
echo number_format(1000255869,0,".",",");
This should work number_format(1000255869, 0, '.', ',');
Try this.Reference
$number= 1000255869;
echo number_format($number);

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

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);

Print numeric values to two decimal places

I'm using PHP's number_format to display floats to 2 decimal places.
When the number is something like 1.898 it gets rounded up to 1.9.
How do I get it to display that as 1.90?
Update:
I have a function that ends...
return number_formant($num, 2);
The php script that calls the function prints out the number to be used by Javascript. When I do a var_dump on the number, it prints correctly with two decimal places. Looks like it's Javascript that's loosing the zero.
Here's the JS code that was causing the issue...
function show_level(level) {
...
if (level > 9999)
level_label = (level / 1000).toPrecision(3) + 'k';
else if (level > 999)
level_label = (level / 1000).toPrecision(2) + 'k';
else
level_label = level;
I altered the last line to get it working how I wanted..
level_label = level.toFixed(2);
Maybe not the best solution but:
$n = 1.2345;
$n = number_format( round($n, 1), 2);
//echo 1.20
echo $n;
So,
you mean something like this (what you have):
<?php
echo number_format($x);
?>
and here is what you want:
<?php
echo number_format($x,2);
?>
you can use other lengths. Try it Out!
Hope could helpya
:)
echo sprintf('%01.2f', number_format(1.898,2))
You can do:
echo round(1.898,2);

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);
