是否有可能在c＃中处理复杂数据类型的更高精度？

Question

I'm writing program which use complex data type, but it's too small for my problem. I know it's just double data type for both real and imaginary members, but is it possible to keep numbers as big as 10^30? I was thinking about about connecting complex struct with big integer type (because I don't use floating-point numbers), but don't know how to do it.

Answer 1

将数字作为字符串进行操作，并逐位计算长计算。

Answer 2

I solved the problem. I made a structure with two BigInteger members, one for real and second for imaginary part. Ofc this solution need to create new functions for complex operations. For example adding 2 Complex (I named struct as "BigComplex")

BigComplex add(BigComplex x, BigComplex y)
{
    BigComplex z;
    z.Real = x.Real + y.Real;
    z.Imaginary = x.Imaginary + y.Imaginary;
    return z;
}
