is_float

IS_FLOAT(3)								 1							       IS_FLOAT(3)

is_float - Finds whether the type of a variable is float

SYNOPSIS

       bool is_float (mixed  $var)

DESCRIPTION

	Finds whether the type of the given variable is float.

       Note

	       To test if a variable is a number or a numeric string (such as form input, which is always a string), you must use is_numeric(3).

PARAMETERS

	      o $var
		- The variable being evaluated.

RETURN VALUES

	Returns TRUE if $var is a float, FALSE otherwise.

EXAMPLES

       Example #1

	      is_float(3) example

	      <?php
	      if (is_float(27.25)) {
		  echo "is float
";
	      } else {
		  echo "is not float
";
	      }
	      var_dump(is_float('abc'));
	      var_dump(is_float(23));
	      var_dump(is_float(23.5));
	      var_dump(is_float(1e7));	//Scientific Notation
	      var_dump(is_float(true));
	      ?>

	      The above example will output:

	      is float
	      bool(false)
	      bool(false)
	      bool(true)
	      bool(true)
	      bool(false)
