The main content of this article is about keeping two decimal points in PHP, which has a certain reference value. Now I share it with everyone. Friends in need can refer to it.
I have been doing statistics recently. I have a lot of exposure to data about numbers.
uses three functions to retain N digits after the decimal. Next, I will briefly introduce the three functions:
1, number_format
echo number_format("5000000")."<br>"; echo number_format("5000000",2)."<br>"; echo number_format("5000000",2,",",".");
The main function of this function is to implement: thousandth grouping formatted data.
Output result
5,000,000
5,000,000.00
5.000.000,00
2, sprintf
$num = 123; $data=sprintf("%.2f",$num); echo $data;
The result is:
123.00
3, round
$num1 = 123.1267 $data1 = round($num1, 2); $num2 = 123 $data2 = round($num2, 2); echo $data1."<br>" echo $data2
The result is:
123.13
123
If this function has less than two decimal points, it will not automatically help you Complete.
