Golang not only provides fundamental data types such as int, float, and string but also supports complex number types, facilitating the handling of complex numbers with ease. There are two variants of complex data types in Golang, namely complex64 and complex128.

Complex64: Precision within Constraints

The complex64 data type in Golang represents a complex number with real and imaginary parts, each using a 32-bit float. Despite its apparent limitation, complex64 remains useful in many contexts. An example of its declaration is as follows:

var myComplex complex64 = 3.14 + 2i

In this example, myComplex stores a complex number with a real part of 3.14 and an imaginary part of 2.

Complex128: Higher Precision

If higher precision is required, Golang provides the complex128 data type. Complex128 uses a 64-bit float for the real part and a 64-bit float for the imaginary part. An example of its usage is as follows:

var myComplex complex128 = 3.14 + 2i

In this example, myComplex stores a complex number with a real part of 3.14 and an imaginary part of 2.

Complex128: Higher Precision

If higher precision is required, Golang provides the complex128 data type. Complex128 uses a 64-bit float for the real part and a 64-bit float for the imaginary part. An example of its usage is as follows:

var myComplex complex128 = 3.14 + 2i

With complex128, we can handle complex numbers with higher precision, which is often crucial in scientific computations or applications requiring a high level of accuracy.
