How to generate random decimals from 0 to 1 through php
Javascript's method of generating random decimals from 0 to 1 can call its own Math.random();
For example:
<script type="text/javascript">document.write(Math.random()); // 0.5840498607140034</script>
There is in php rand,mt_randrandom methods, but neither of these two methods can generate 0~1 random decimals. We can write a method to achieve this function.
The method for php to generate random decimals from 0 to 1 is as follows:
<?php/** * 生成0~1随机小数 * @param Int $min * @param Int $max * @return Float */function randFloat($min=0, $max=1){ return $min + mt_rand()/mt_getrandmax() * ($max-$min); }// 例子,创建5个0~1随机小数for($i=0; $i<5; $i++){ echo randFloat().'<br>'; }?>
Output:
0.59804026251568 0.67772196544228 0.90589751205682 0.45087858822703 0.17475316774787
