I have never done this before but I think I can learn it, I think it has something to do with echo and if I can add both files to that part, I read something about arrays too but I am not sure that will apply here. If I take off line and add the file name instead will that change the outcome?

floatval - Get float value of a variable

SYNOPSIS
float floatval (mixed $var) DESCRIPTION
Gets the float value of $var. PARAMETERS
o $var - May be any scalar type. floatval(3) should not be used on objects, as doing so will emit an E_NOTICE level error and return 1. RETURN VALUES
The float value of the given variable. Empty arrays return 0, non-empty arrays return 1. Strings will most likely return 0 although this depends on the leftmost characters of the string. The common rules of float casting apply. EXAMPLES
Example #1 floatval(3) Example <?php $var = '122.34343The'; $float_value_of_var = floatval($var); echo $float_value_of_var; // 122.34343 ?> Example #2 floatval(3) non-numeric leftmost characters Example <?php $var = 'The122.34343'; $float_value_of_var = floatval($var); echo $float_value_of_var; // 0 ?> SEE ALSO
boolval(3), intval(3), strval(3), settype(3), Type juggling. PHP Documentation Group FLOATVAL(3)
