PHP - Convert integer variable value to decimal

Question

I have a variable fl_duration which takes integer value 1,2,3. I am looking to create a new variable 'decimal' which will return the value as a decimal number i.e. 0.1 , 0.2, 0.3.

$decimal = get_field('fl_duration');

Any ideas would be much appreciated.

it's only 1,2,3 - no other values, so I shouldnt worry about that — JoaMika

What about dividing by ten? like function dec($flDur) {return $flDur/10;}; $decimal = dec($fl_duration); — helvete

PHP will convert it to an float itself so you can just do it by basic math.

<?php

$int = 1;
$dec = $int / 10;
var_dump($int);
var_dump($dec);

Output:

int(1)

float(0.1)

How about number_format(), is this what you are looking for? http://php.net/manual/en/function.number-format.php

$decimal = number_format( 1, 2); //will give you string(4) "1.00"

You can also do it like this:

$int = 1;
$dec = (float) "0.$int";
// or
$dec = (double) "0.$int";
var_dump($dec);

Output:

float(0.1)
