PHP Random # Generator

Not a HW problem btw.


I am just doing some simple php for a website and I want a random number from 6 to 10 to show with 2 decimal places, ie 7.49.

this is the code i have but the decimals just all show .00 (6.00, 7.00, 8.00, etc)

<?php $number=rand(6.00,10.99);  

echo number_format($number,2);

 ?>

That's because rand() returns an integer. For a number between 6.00 and 10.99 inclusive, I'd do this:

$number = 6.0 + (rand(0, 499) / 100.0);

Thanks, that worked!

That's great news. Good luck with your project!
