strDataTemp.Format("%f;", pLin->m_AquireIAndVThread.fAverageI)如果要对fAverageI执行(-0.0004,0.0001)时取0判断,应该加在什么位置

你可以在调用 `Format` 函数之前,对 `fAverageI` 进行处理。具体来说,可以使用三目运算符对其进行判断,如果在 (-0.0004, 0.0001) 之间,则将其赋值为 0。示例如下:
```
float fValue = pLin->m_AquireIAndVThread.fAverageI;
fValue = (fValue > -0.0004 && fValue < 0.0001) ? 0 : fValue;
strDataTemp.Format("%f;", fValue);
```
这样,在调用 `Format` 函数时,`fAverageI` 的值就已经被处理过了,如果在 (-0.0004, 0.0001) 之间,则被赋值为 0,否则保持原来的值。

//float fValue = pLin->m_AquireIAndVThread.fAverageI; pLin->m_AquireIAndVThread.fAverageI = (pLin->m_AquireIAndVThread.fAverageI > -0.0004 && pLin->m_AquireIAndVThread.fAverageI < 0.0001) ? 0 : pLin->m_AquireIAndVThread.fAverageI; strDataTemp.Format("%f;", pLin->m_AquireIAndVThread.fAverageI);/ strSaveData += strDataTemp;改写成if else 语句
可以将代码改写成如下if-else语句:
```
float fValue = pLin->m_AquireIAndVThread.fAverageI;
if (pLin->m_AquireIAndVThread.fAverageI > -0.0004 && pLin->m_AquireIAndVThread.fAverageI < 0.0001) {
pLin->m_AquireIAndVThread.fAverageI = 0;
} else {
pLin->m_AquireIAndVThread.fAverageI = pLin->m_AquireIAndVThread.fAverageI;
}
strDataTemp.Format("%f;", pLin->m_AquireIAndVThread.fAverageI);
strSaveData += strDataTemp;
```
其中,如果pLin->m_AquireIAndVThread.fAverageI的值大于-0.0004且小于0.0001,则将其赋值为0;否则保持其原有的值不变。最后将该变量的值转换为字符串类型,并添加到strSaveData这个字符串变量中。
strDataTemp.Format("%f;", pLin->m_AquireIAndVThread.fAverageI)如果要对fAverageI执行(-0.0004,0.0001)判断,应该加在什么位置
你可以在调用 `Format` 函数之前添加一个判断语句,比如:
```cpp
if (pLin->m_AquireIAndVThread.fAverageI >= -0.0004 && pLin->m_AquireIAndVThread.fAverageI <= 0.0001) {
strDataTemp = "the value of fAverageI is within the range of (-0.0004, 0.0001)";
} else {
strDataTemp.Format("%f;", pLin->m_AquireIAndVThread.fAverageI);
}
```
这样,如果 `fAverageI` 的值在指定的范围内,就输出一段提示信息;否则,就按照原来的代码格式化输出。
