Why is PHP printing my number in scientific notation, when I specified it as .000021?

Question

In PHP I have the following code:

<?PHP   $var = .000021;   echo $var; ?> 

the output is 2.1E-5 !

Why? it should print .000021

Answer 1

Use number_format() to get what you're after:

print number_format($var, 5); 

Also check sprintf()
