[英]Trailing zeroes in PHP
I have a value $rating
that is between 0.00 and 10.00. 我的值$rating
在0.00和10.00之间。
I need to add trailing zeroes to numbers like 3.70 (which is 3.7) and 5.00 (which is 5). 我需要将尾随零添加到3.70(即3.7)和5.00(即5)之类的数字上。 Do I need some kind of if statement too to check what value $rating
is and then do some kind of str_pad
? 我是否还需要某种if语句来检查$rating
值,然后执行某种str_pad
? I'm not sure what to do. 我不确定该怎么办。
See the number_format
function 参见number_format
函数
echo number_format(5, 2); // returns 5.00
echo number_format(5.2, 2); // returns 5.20
echo number_format(5.24, 2); // returns 5.24
尝试使用number_format,如下所示:
number_format((float)$yourNumber, 2, '.', '');
