{
	Creates a CFNumber with the given value. The type of number pointed
	to by the valuePtr is specified by type. If type is a floating point
	type and the value represents one of the infinities or NaN, the
	well-defined CFNumber for that value is returned. If either of
	valuePtr or type is an invalid value, the result is undefined.

	Returns the storage format of the CFNumber's value.  Note that

{
	Copies the CFNumber's value into the space pointed to by
	valuePtr, as the specified type. If conversion needs to take
	place, the conversion rules follow human expectation and not
	C's promotion and truncation rules. If the conversion is
	lossy, or the value is out of range, false is returned. Best
	attempt at conversion will still be in *valuePtr.
}
function CFNumberGetValue( number: CFNumberRef; theType: CFNumberType; valuePtr: UnivPtr ): Boolean; external name '_CFNumberGetValue';

{
	Compares the two CFNumber instances. If conversion of the
	types of the values is needed, the conversion and comparison
	follow human expectations and not C's promotion and comparison
	rules. Negative zero compares less than positive zero.
	Positive infinity compares greater than everything except
	itself, to which it compares equal. Negative infinity compares
	less than everything except itself, to which it compares equal.
	Unlike standard practice, if both numbers are NaN, then they
	compare equal; if only one of the numbers is NaN, then the NaN
	compares greater than the other number if it is negative, and
	smaller than the other number if it is positive. (Note that in
	CFEqual() with two CFNumbers, if either or both of the numbers
	is NaN, true is returned.)
