Precision of floating point numbers

[mostafatalebi]

Hello everybody

 

I have a super simple question

 

I do a math operation (division) which result (naturally) in a long decimal trail. I need only one decimal. Example: 1.5 or 2.6 and not 3.08 or 5.457874.

 

Thanks in advance

Implement round with the second precision parameter set to 1

Also, there's a couple of alternatives when outputting the number

 

$num = 3.456;
  // either
echo number_format($num, 1);    //--> 3.5
  // or
printf('%0.1f', $num);    //--> 3.5
