floatval

FLOATVAL(3)								 1							       FLOATVAL(3)

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
	      ?>
