Remarks
• These functions can be used in the COMP Mode.
• The
r
-value or
x
-value produced by the calculation is assigned to variable I, while the
Ƨ
-value or
y
-value is assigned to variable J (page 34).
• 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 coordinate that the conversion produces (
r
-value or
x
-value).
Example: Pol (
'
2,
'
2 ) + 5 = 2 + 5 = 7
