How to display floating point number from table show as digit format

In my table i have the record value 0.0000009 like this since i run my program i got result like this 9.0E-7. But i need to display 0.0000009 this format.
<?php echo $a=0.0000009; ?>

Kindly guide me 

A:

You can use formatting print, %f means that you bind float value, "1" symbols before point, "8" after point:
echo sprintf('%1.8f', 0.00000009);
