Polar
is a display-format instruction, not
a conversion function. You can use it only at the

Degree angle mode returns (r

).
•
Radian angle mode returns r e i q .
complexValue
can have any complex form.
However, an r
e
i q
entry causes an error in Degree
angle mode.
Note : You must use the parentheses for an (r
