converting String to double or float

[nevarmore]

I'm starting with a string of raw data coming in from a device on the serial port. I have stripped that string down to the single number that I need, how do I go about converting that number from a string representation to a float or a double??

Regular typecasting does not work, as in:

float myFloater = (float)(myString);

try the itoa function....

doesnt that only work on integers? I think there is an implementaion of itofp(or something like that) in the K&R to convert them from floating point.

That narrows down the search. Thanks guys, ill let you know what it is for sure.

actually...this is C#, for some reason I thought this was the C++ forum. In C# there is probably a more accurate method for conversion.

you have to parse the string. I had to parse it as a double then cast it to a float, because for some reason there isn't a float class in the System namespace.

double dblNum = System.Double.Parse( Console.ReadLine() );
float fltNum = (float)dblNum;

I tried this and it worked for me. Hope this helps.

I think it might. I'll let you know in a few weeks when I have a break from classes to work on my own projects. :D

double fromStrToDbl = Convert.ToDouble("200");
float numberFlt = (float)fromStrToDou

will also work

Thanks for posting that. This project has been pushed so far on the back burner its about to fall of the stove!!
