How to round figure of echo sum value

<?php echo (90+10)*15*732/365/30 ;   ?>

this code showing like this

100.27397260274

and I want like this

100.300

and I am using like this but this is also not working

<?php echo ((round((90+10)*15*732/365/30, 1)),3) ;   ?>

how can I do this?

Answer 1

Do this:

<?php echo round( (90+10)*15*732/365/30 , 2 ); ?>

and the output will be:

100.27

and for 100.3 you can do

<?php echo round( (90+10)*15*732/365/30,1 ); ?>

and for 100.300 you need to use extra function number_format() with the 3 for the value of decimals:

<?php echo number_format( round((90+10)*15*732/365/30,1), 3 ); ?>

Answer 2

round(number,decimal_place);
