Master the plural types of Go language and easily handle mathematical calculations

The complex number type complex128 in the Go language is used to represent complex numbers with real and imaginary parts. It is created by var c complex128 = a bi. It supports operations such as addition, subtraction, multiplication, and division. It is especially suitable for geometric calculations, such as solving between points. Distance has a wide range of applications in science and engineering.

Master the plural types of Go language and easily handle mathematical calculations

In Go language, the plural typecomplex128 can be used to represent objects with real values. The plural of part and imaginary part. Complex number types are widely used in fields such as mathematical computing, scientific modeling, and signal processing.

Creating complex numbers

The Go language provides a convenient method to create complex numbers:

var c complex128 = 3 + 4i

Here, 3 is the real part, 4i is the imaginary part. i is a plural unit, equal to sqrt(-1).

Complex number operations

The Go language provides a rich set of operators for performing complex number operations:

• Addition:
• Subtraction: -
• Multiplication: *
• Division: /
• Modulo: %

Practical Case: Complex Number Geometry

Complex numbers are particularly useful when solving geometric problems. For example, we can use complex numbers to represent the coordinates of a point on a two-dimensional plane:

type Point struct {
    X complex128
    Y complex128
}

// 求解两点之间的距离
func (p1 Point) DistanceTo(p2 Point) complex128 {
    return c.Sqrt(c.Pow(p2.X-p1.X, 2) + c.Pow(p2.Y-p1.Y, 2))
}

Summary

The complex number type of the Go language provides us with powerful tools for processing mathematical calculations. It supports a variety of operations and can be used to solve complex geometric problems. Mastery of complex number types will be of great benefit in scientific computing and engineering applications.
