With PHP, how to check if decimal number is above or less than 50?

Question

I am trying to check if a number which is inside a variable got a decimal number above 50 , or less than 50. Then depending on if it's 50 or higher, round the decimal number to 99 , and if it's less, round it to 00.

Here is a piece of my code:

public function roundPrice($price)
{
return round( (ceil($price) - 0.01), 2);
}

It makes all decimal numbers round up to 99 . I would need only decimals which are 50 or higher to be rounded in 99, and 49 or less become 00.

How could I achieve this in PHP ? Many thanks, I'm stuck here and don't know much how to do that.

Answer 1

On the off chance OP actually meant decimal places where 1.36 becomes 1.00 and 1.60 becomes 1.99.

Probably more elegant solutions, but here's one:

function roundPrice($price)
{
    $intVal = intval($price);
    if ($price - $intVal < .50) return (float)$intVal;
    return $intVal + 0.99;
}

Answer 2

I would need only decimals which are 50 or higher to be rounded in 99, and 49 or less become 00.

Strange requirement but:

public function roundPrice($price)
{
  return $price >= 50 ? 99 : sprintf("%02s", 0);
}

For numbers greater than or equal to 50, it would return 99 and for numbers less than 50, it would return 00

Answer 3

You're not really rounding, so just be direct about it.

public function roundPrice($price)
{
    if($price >= 50)
    {
        return 99;
    }
    else
    {
        return 0;
    }
}

Your stated problem does not handle the $price being equal to 50. I made the assumption that the value of exactly 50 rounds up to 99.

Answer 4

This modifies your function to return the decimal value if it's 50 or above and 0 otherwise.

public function roundPrice($price)
{
   $decValue = round( (ceil($price) - 0.01), 2);

   if ($decValue >= 50) return $decValue;
   else return 0;
}

Answer 5

I think you want this:

public function roundPrice($price) {
    $p = round($price, 0);
    if( ceil($price) == $p) {
        return $p - 0.01;
    }
    return $p;
}

This returns X.99 for values >= X.5 and X.00 for all other values.
