请帮我翻译一下

[cs_victor]

public double numinput=0;
public bool dot = false;
if(textBox1.Text.Equals("0.")&& !dot) textBox1.Text="1";
else textBox1.Text = textBox1.Text+"1";
numinput = double.Parse(textBox1.Text);



主要是dot在这里的用途不太理解。

[王集鹄]

dot不就是点的意思吗
估计是记录用户是否输入小数点的意思
找找其他赋值的地方

是不是计算器的代码？
“0.”为默认值
用户如果按了“.”界面还是显示“0.”再按“1”就要合成“0.1”
如果没有按“.”就将是“1”

[andylauhai]

楼上有道理

[cs_victor]

是我写的计算器 上面的是我参考别人的 不太理解
我不太懂那个bool dot =false; 在下面的语句中的含义，
还有if(textBox1.Text.Equals("0.")&& !dot) textBox1.Text="1";中的！dot的作用是什么啊
请赐教```

你要去别的地方看看通过什么给dot赋值的，这里的代码看不出dot的作用。

我怎么也看着迷糊啊啊 。。好像!dot是什么意思？
是不是“没有“点”的意思啊” 但是没有给dot赋值啊

这是我写的程序，上面的问题就是这里的 ：
