Only display decimals if they're present

[davidcriniti]

Hi guys,

 

I've got a line of code that asks for a column called "distance_completed" to be displayed as part of a string.

 

This column tells users how far people have run in a running race.

 

I set up this field in my database to 11,3 so all distances appear with a decimal at the end, and then 3 digits after the decimal place.

 

How would I alter the code so that the numbers that don't have any information in the places section just appear as integers Eg: 42 instead of 42.000 (for someone who ran exaclty 42km) and those that do have information in the decimal places appear correctly (eg: if a person ran 42km and 195m, it would appear as 42.195).

 

I think this is probably the only line of code that would need modification:

 

echo ($row['time'] != null)?$row["time"]:"dnf at ".$row["distance_completed"]."km.";

use the round() function if you want an integer instead of a decimal, you can round it when you echo the distance or when you insert into the db...

...but I don't necessarily want to round it off. Eg: If the value was 42.195, I'm happy to keep it that 42.195.

 

I'd only like numbers changed when there is no information on the right-hand-side of the decimal.

 

Eg: If someone ran exactly 20km, I'd like to see 20      ....rather than 20.000

 

Not sure if this is possible or not?

use rtrim()

 

i.e. rtrim($string, "0"); then you'll have to remove decimal aswell

You can just specify the decimal in the rtrim character list, too.

 

rtrim($num, '0.');

 

$num = array(1.0001, 1.00, 3.3345, 4.0, 5.55, 6.7800000000);
foreach( $num as $v ) {
rtrim($v, '0.');
echo $v . '<br>';
}
// RETURNS:
/*
1.0001
1
3.3345
4
5.55
6.78
*/
