ABSTRACT:
A calculation section performs a simplified calculation to obtain lengths and/or angles using calculations of addition and multiplication, without using calculations of division, square root and inverse trigonometric function that impose heavy load to the hardware. A data storage section stores reference length data and reference angle data in a data format that is appropriate for the simplified calculation.
