I have the following conundrum. In C#, I want to store a rational and get a string representation of it's decimal notation.
Normally I would just use float or double to store the number and get the string but I would like a "high resolution" decimal notation. The double data type only gives about 16 characters at best in it's string representation. I am looking for the string representation of the decimal notation to contain many more characters, around 30-50 would be ideal. I need the "high resolution" to check for repeating sub-sequences.
The rational number might be simple but I would like the string representation to be very detailed
Example: 1/7 => 0.1428571428571428571428571428
My Question: Is there a C# data structure in the .NET libraries that will store and print rational numbers like I described above?
The Base Class Library's CodePlex site contains a BigRational type, which provides " an arbitrary-precision rational number type." This should provide the detail and precision you wish.
