hey! I am wondering if anybody could help me with a problem: How to convert Ansi String of a form: String Element = "1.75627e+23"; to a double?

std::stringstream converter;converter << your_ansi_string.c_str();double output;converter >> output;

You may wish to check whether the read was successful by testing the converter stream after the operation (is it empty? is it in a valid state?)

If you're going to be doing this kind of conversion at all frequently, you might consider overloading

operator<<

and

operator>>

for this ANSI String.

acctually I have used:

String.ToFloat()

Are they going to be any problems with it?
