描述

Problem Statement Windows Calculator currently does not support imaginary numbers. Instead, we show "Invalid input":

Evidence or User Insights The complex number system is part of US high school common core curriculum. According to some reports in the Math Educators Stack Exchange, complex numbers are taught in at least some high school level math and science courses in China, Norway, Italy, India, Israel, and the UK.

Proposal Add support for imaginary numbers in Scientific mode of Windows Calculator.

Goals

  • Add support for output that includes imaginary numbers (e.g., √(-16) = 4 i)
  • Add support for inputting expressions with imaginary numbers (e.g., i2 = -1)
  • Add i to the keyboard

Non-Goals

  • Support for imaginary numbers outside of Scientific mode

Requested Assignment I'm just suggesting this idea. I don't want to implement it.

研究方向
Examine the Windows Calculator source code, particularly the scientific mode computation engine. Identify where currently invalid inputs like √( 16) are handled and how to extend to support complex numbers. Look at existing number representation and display logic.
