PHP implementation method of generating 0~1 random decimals

This article mainly introduces the PHP implementation to generate 0~1 random decimal method, interested in the friend's reference, I hope to help you.

JavaScript generates 0~1 random decimals in a way that calls its own math.random ();

For example:

<script type= "Text/javascript" >document.write (Math.random ()); 0.5840498607140034</script>

There are Rand,mt_rand random methods in PHP, but neither of these methods generates 0~1 random decimals, and we can write a method to implement this function.

PHP generates 0~1 random decimal methods as follows:

<?php/** * Generate 0~1 random decimals * @param int  $min * @param int  $max * @return Float */function randfloat ($min =0, $max =1) { C2/>return $min + mt_rand ()/mt_getrandmax () * ($max-$min);} example, create 5 0~1 random decimals for ($i =0; $i <5; $i + +) {  echo randfloat (). ' <br> ';}? >

Output:

0.598040262515680.677721965442280.905897512056820.450878588227030.17475316774787

The above is the whole content of this article, I hope that everyone's study has helped.
