Experts is there a function out there that will convert a string with an exponential component into a float?<br />
<br />
1.902922E+01 -- i need to extract this from a file and store at as a float variable...<br />
<br />
I am struggling to find someway of doing this - note that the format of the string is always the same - 6 numbers after the decimal point, then the E, then power term..

Convert a string to float

Development in most programming languages is frequently done with an editor or integrated development environment (IDE). An IDE is a software application that provide comprehensive facilities to computer programmers for software development. An IDE normally consists of a source code editor, build automation tools and a debugger. XCode, Visual Studio, Adobe Dreamweaver and Eclipse are some of the more popular development tools, but an editor or IDE can be anything from simple text editors to sophisticated programs.

Editors IDEs

Microsoft Visual C++ (often abbreviated as MSVC or VC++) is an integrated development environment (IDE) product from Microsoft for the C, C++, and C++/CLI programming languages. It features tools for developing and debugging C++ code, especially code written for the Microsoft Windows API, the DirectX API, and the Microsoft .NET Framework. Many applications require redistributable Visual C++ packages to function correctly and are often installed independently of applications, allowing multiple applications to make use of the package while only having to install it once

Visual C++.NET

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.
