Plural Calculator

How to Use?

• Press the i key to set the real and imaginary parts of a complex number, or press the ∠ key to set the amplitude and angle (in degrees) of a complex number.
• Use the arrow keys ← → to freely set two parameters of complex numbers, just like Casio Calculator. After editing the second parameter, press → again to finish editing.
• Use the +/- button to set whether a number is positive or negative.
• The yellow DEL key means backspace, and the red AC key means clear all.
• Calculator allows arithmetic calculation. But if you accidentally let 0 be the divisor, there will be an error!
• Press the a+bi key to display the complex number of polar coordinate mode as Cartesian coordinate mode, which is convenient for viewing the real part and imaginary part; Press the A∠θ key to display the complex number of Cartesian coordinate mode as polar coordinate mode, which is convenient for viewing the amplitude and angle.
• Pressing = will draw the result in the "Complex Plane" tab.

复数计算器

使用方法

• 按下 i 键设置复数的实部和虚部，或按下 ∠ 键设置复数的振幅和角度（采用角度制）。
• 使用方向键 ← → 自由设置复数的两个参数，就像“卡西欧计算器”那样。编辑完第二个参数后，再次按下 → 结束复数编辑模式。
• 利用 +/- 设定一个数为正数或负数。
• 黄色的 DEL 键表示退格，红色的 AC 键表示全部清除（归零）。
• 计算器允许使用四则运算。但如果你不小心让 0 作为除数，将会出现错误！
• 按下 a+bi 键，将极坐标模式的复数显示为笛卡尔坐标模式，便于查看实部、虚部；按下 A∠θ 键，将笛卡尔坐标模式的复数显示为极坐标模式，便于查看振幅、幅角。
• 按下 = 的同时会在“复平面”标签页中画出结果。
