Convert integer numbers into a specific float numbers in PHP array

Question

I have an array that has random integer numbers and I want to convert them into float numbers but I want to put decimal point after first two digits only. Following is my array:

[143] => Array
    (
        [0] => 723579
        [1] => 112338261
    )

[144] => Array
    (
        [0] => 723575
        [1] => 11233847
    )

[145] => Array
    (
        [0] => 723575
        [1] => 11233
    )

And I want the output to be the following.

[143] => Array
    (
        [0] => 72.3579
        [1] => 11.2338261
    )

[144] => Array
    (
        [0] => 72.3575
        [1] => 11.233847
    )

[145] => Array
    (
        [0] => 72.3575
        [1] => 11.233
    )

I think that I can manipulate it through string modification first and convert it into float number. Is there any easiest or simple way to manipulate it in PHP?

You seem to misunderstand what a "round number" is. Your input contains round numbers, the output contains fractions. — Barmar

Use nested foreach loops. Use reference variables so you can modify the original arrays. Insert a . after the second digit, then convert that to a float.

foreach ($array as &$nested_array) {
    foreach ($nested_array as &$val) {
        $val = floatval(substr($val, 0, 2) . "." . substr($val, 2));
    }
}
