tCoord operator *	(	REAL	a,
		tCoord const &	c
	)			[inline]

stretches a coordinate by a factor from the center

Definition at line 157 of file tCoord.h.

                                                 {
    return c*a;
}

std::ostream& operator<<	(	std::ostream &	s,
		const tCoord &	c
	)			[inline]

Parameters:

	s	the stream for the coordinate to be inserted into
	c	the coordinate to be inserted

Returns:

the stream given in s

Definition at line 143 of file tCoord.h.

References tCoord::Print().

    c.Print(s);
    return s;
}

std::istream& operator>>	(	std::istream &	s,
		tCoord &	c
	)			[inline]

Parameters:

	s	the stream for the coordinate to be read from
	c	the coordinate to be read

Returns:

the stream given in s

REAL se_EstimatedRangeOfMult	(	const tCoord &	a,

Here is the caller graph for this function:

REAL st_GetDifference	(	const tCoord &	a,
		const tCoord &	b
	)

returns a measure for the equality of two coords
