Notes
• These functions can be used in the COMP, SD, and REG Modes.
• Calculation results show the first
r
value or
x
value only.
• The
r
-value (or
x
-value) produced by the calculation is assigned to variable X, while the
-value (or
y
-value) is assigned to variable Y (page 16). To view the
-value (or
y
-value),
display the value assigned to variable Y, as shown in the example.
• The values obtained for
when converting from rectangular coordinates to polar
coordinates is within the range –180°<
<
180°.
