Notes
• These functions can be used in the COMP, SD, and REG Modes.
• Calculation results show the fi rst
r
value or
x
value only.
• The
r
-value (or
x
-value) produced by the calculation is assigned to variable X, while the
Ƨ
-value (or
y
-value) is assigned to variable Y (page 22). To view the
Ƨ
-value (or
y
-value),
display the value assigned to variable Y, as shown in the example.
• The values obtained for
Ƨ
when converting from rectangular coordinates to polar
coordinates is within the range –180°<
Ƨ
<
180°.
• When executing a coordinate conversion function inside of a calculation expression, the
calculation is performed using the fi rst value produced by the conversion (
r
-value or
x
-
value).
