The HTML code is as follows, executes m_num & lt; M_str. ToDouble () returns the result is true, best can not, please explain greatly,

CodePudding user response:

The results should be this also

CodePudding user response:

You change which is a step in the right
If (m_num & lt; M_num2)
Caption=1;
The else
Caption="2";

CodePudding user response:

refer to the second floor ksrsoft response:

If (m_num & lt; M_num2)
Caption=1;
The else
Caption="2";

To ask, why can't use this way to determine if (m_num & lt; M_str. ToDouble ())?

CodePudding user response:

Really strange, the estimate is a bug
