Using a Command to Specify the Calculation
Result Format
Either of two special commands (
rθ 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 = 245, 245 = 2 + 2i (MthIO-MathO) (Angle unit:
Deg)
2 2 (i) (CMPLX)
( rθ)
245
2 () 45 (CMPLX) ( a+bi) 2+√2i
Statistical Calculations (STAT)
