将长数字缩短为 K/M/B? [英] Shorten long numbers to K/M/B?

问题描述

我在谷歌上搜索了很多，但根据我的查询我找不到任何有用的功能.

我想要的是:

100 ->1001000 ->1,000142840 ->142,840

但是

2023150 ->2.023M(为了更准确，我还需要 3 个额外的数字)5430120215 ->5.430B

如果可能，我非常感谢任何自定义函数来动态选择限制.

谢谢！

解决方案

使用 number_format():

if ($n <1000000) {//小于一百万$n_format = number_format($n);} else if ($n <1000000000) {//任何小于十亿$n_format = number_format($n/1000000, 3) .'M';} 别的 {//至少十亿$n_format = number_format($n/1000000000, 3) .'乙';}

如果限制"是指小数位数(精度)，那很简单:

function custom_number_format($n, $precision = 3) {如果 ($n <1000000) {//小于一百万$n_format = number_format($n);} else if ($n <1000000000) {//任何小于十亿$n_format = number_format($n/1000000, $precision) .'M';} 别的 {//至少十亿$n_format = number_format($n/1000000000, $precision) .'乙';}返回 $n_format;}

I've googled this a lot but i can't find any helpful functions based on my queries.

What i want is:

100 -> 100
1000 -> 1,000
142840 -> 142,840

BUT

2023150 -> 2.023M ( i still want 3 additional numbers for more accuracy )
5430120215 -> 5.430B

I would totally appreciate any custom functions to dynamically choose the limit if possible.

Thanks!

解决方案

Use number_format():

if ($n < 1000000) {
    // Anything less than a million
    $n_format = number_format($n);
} else if ($n < 1000000000) {
    // Anything less than a billion
    $n_format = number_format($n / 1000000, 3) . 'M';
} else {
    // At least a billion
    $n_format = number_format($n / 1000000000, 3) . 'B';
}

I would totally appreciate any custom functions to dynamically choose the limit if possible.

If "limit" refers to the number of decimal places (the precision), that's easy:

function custom_number_format($n, $precision = 3) {
    if ($n < 1000000) {
        // Anything less than a million
        $n_format = number_format($n);
    } else if ($n < 1000000000) {
        // Anything less than a billion
        $n_format = number_format($n / 1000000, $precision) . 'M';
    } else {
        // At least a billion
        $n_format = number_format($n / 1000000000, $precision) . 'B';
    }

    return $n_format;
}
