Return the floating point equivalent

$value: A string with a leading number, or a number (int or float)

Floating point value, or:

• 0 on failure (for example, a string without a numeric in the leftmost characters)
• 0 on empty array
• 1 on non-empty array

Convert the integer '1' into a float variable which has a value of 1.000000:

<?
  $x=1;
  $f=floatval($x);
  print("The float value of ".$x." is ".$f);
?>

The above example will output:

The float value of 1 is 1.000000
