I need a function to do the following, I get the number for example 15, and I need to turn it into a decimal 1.0, rounding the 5 to 0.

I tried to use the number_format(15, 1, '.', ''), but he returns me 15.0

How can I do that?

    to make rounding you must use the function intval(), see also other mathematical functions. A simple division will solve the problem: intval(15 / 10)

  • You typed 15, which is an integer number. Try changing the number to 1.5 to test

Something like that?

<?php

$a = 15;
$b = $a / 10; //1,5
$c = floor($b); //1  - arredonda para baixo

var_dump($a, $b, $c); //para você verificar a transformação do número

echo number_format($c, 1, '.', ''); //para exibir '1.0'

other functions for rounding is the round and the Ceil

  • The result of var_dump is int(15) float(1.5) float(1)

  • i know the result, I wrote the code. I’m showing the number transformation

    Adir I know you know the result, but whoever comes to see the question does not know.
