Numeric expression
®
1) Transforms rectangular coordinates (x ,
y) to polar coordinates (r , 8)
using
the following relational expressions.
2) The
r
coordinate of
(r ,
8) is given as the output of the function, and the
value of the
r
coordinate will be assigned to variable X and the value of the 8
coordinate will be assigned to variable Y at the same time .
3) Calculation of the
8
coordinate will correspond to the angle unit (DEG, RAD
or GRA). The value of
8
will be given within the following range .
DEG: -180° < 8
~
180°
RAD :
-7T

4) An error will occur when
lx l
+
ly l
=
0.
