Trying to add +20% to an amount but...

$worth = 400000000*1.2;

It's giving me 4.8E+8
Why doesn't it give me a proper number?

 

Don't know why...

<?php 

$worth = 400000000*1.2;

echo $worth;

?>

PHP:

Seems to work for me.

 

Must be some server side option then, I'm testing this on my local Mamp server. Anyone knows what setting this could be?

 

Really weird. It's working with 400000001, but not with 400000000.

 

echo intval($worth);

 

Try this on the Cli

php -r "echo ini_get('precision');"

Code (markup):

Mine is set at 12 and I get the result of 480000000 for 400000000*1.2.

If I reduce the precision to fewer digits

ini_set('precision', 2);
echo 400000000*1.2;

PHP:

PHP switches to scientific notation, replicating your issue.

 

that's the one - 'E' in this case just means 4.8 * 10 to the power of 8.
