Question

I have some problem regarding converting/truncating a number.

This is the condition:

x.35 where x is any decimal number. If the decimal number is less than or equal to 35 then convert the .35 into 99 and subtract the x value with 1.

Something like this:

45.35 will become 44.99

Any help will be much more appreciated!

Answer 1

There’s probably a faster way that doesn’t use the explode function and other unnecessary things, but here’s my rendition of it.

    <?php
    $input = 45.35; //input, obviously
    $in2 = explode(".", $input);

    if($in2[1] <= 35) {
    $in2[1] = 99;
    }

    $output = $in2[0] . "." . $in2[1];
    ?>
