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 + √2i = 2∠45, √2∠45 = 1 + i (MthIO-LineO) (Angle unit:
Deg)
