Question

在我科学型计算器java程序中怎样添加一个度数的功能，就是将数字转为度数，然后可以求三角函数，代码再发

else if (e.getSource() == buttonOthers[scERATIONS.OP_sin.ordinal()])
{

z=Math.sin(Double.parseDouble(outputField.getText()));
str = String.valueOf(z);
outputField.setText(str);
}
else if (e.getSource() == buttonOthers[scERATIONS.OP_cos.ordinal()])
{

z=Math.cos(Double.parseDouble(outputField.getText()));
str = String.valueOf(z);
outputField.setText(str);
}

Answer 1

数字转为度数？ java中math.sin等后面是弧度数，所以输入若是度数将其转为弧度就好

Answer 2

Math.sin(double a) Math.cos(double a) ...
