Reading float values from a file??

Hi, been looking at the tutorials and it only tells you how to read in charchters, is there a way to ready floats in from a file of numerical data, or if not a way to convert the char data into floating point after reading it in, thanks Neil

Assuming a file called file.txt that has the following contents (as an example):

Code:

3.457

This would be all you needed to read that value in a program.

Code:

#include <fstream>

...

std::ifstream input("file.txt");
float fValue;

input >> fValue;

That is for floating point values represented as text in a file. If you are talking about binary data then the process is going to be a bit different.
