Generate Random Decimals

[smithmr8]

How do I generate random numbers.

 

Im looking to generate random numbers between 0.01 and 5.00

 

Thanks

PHP can't generate random numbers with decimals (to my knowledge). But you can generate an integer and divide it by 100

 

<?php
  $num = rand(1,500) / 100;
  echo $num;
?>

You use the rand() function which generates random integers, then divide by 100 and use the result

<?php
$x = rand(1,500)/100;
echo number_format($x,2);
?>

Ah, I see. Thanks

Is there an echo in this room or is it just me?

I was posting my answer at about the same time you posted yours. When I started to post, there were no answers posted.
