Using a Command to Specify the Calculation
Result Format
Either of two special commands (
r
∠
θ
or
a
+
bi
) can be input at the end
of a calculation to specify the display format of the calculation results.
The command overrides the calculator's complex number format setting.
Example:
√2 + √2
i
= 2
∠
45, 2
∠
45 = √2 + √2
