ComplexType type in GolangThe ComplexType type in Golang documentation is a placeholder for two complex number data types:
complex64complex128Both these data types take 2 floating point literals, one for the real part and one for the imaginary part. complex64 takes 2 float32 literals, whereas complex128 takes 2 float64 literals.
ComplexType typeThe following code demonstrates the use of ComplexType:
package mainimport "fmt"func main() {var a complex64 = complex(1, 2)var b complex64 = 2 + 4ivar c complex64 = b - afmt.Println(a)fmt.Println(b)fmt.Println(c)}
In the example above, the variables a, b, and c are of complex64 type (which is a ComplexType). The variable a is created using a built-in complex function which has the following syntax:
func complex(real, imaginary FloatType) ComplexType
The above function takes in 2 floating point numbers (real and imaginary parts) and returns the complex number.
The variable b is created by writing 2 + 4i, just like how you write complex numbers in math. The variable c is created by subtracting a from b, which results in 1 + 2i.
Note: Two variables, one with
complex64type and the other withcomplex128type, cannot be arithmetically compared with each other.
