Does anyone know how to get a random number with a lower bound of 0.0001 and an upper bound of 100.0000 ?
This would help me greatly, thank you

Dunno if this results in what you desire, but a good start perhaps:
Code: Select all
<pre>
<?php
$upperBound = 100.0000;
$lowerBound = 0.0001;
$range = $upperBound-$lowerBound;
$num = $lowerBound + $range * mt_rand(0, 32767)/32767;
echo round($num,4);
?>

Hmm... looks like it could work. I don't need the code for a couple of days, I'm just asking so I don't have to wait when I do need it
If anyone else has alternative methods, then that could still help incase this one doesn't work.
Thank you
