 # 复数
+
+### 创建复数
+[num::complex::Complex](https://autumnai.github.io/cuticula/num/complex/struct.Complex.html) 可以帮助我们创建复数，其中实部和虚部必须是一样的类型。
+
+```rust,editable
+fn main() {
+    let complex_integer = num::complex::Complex::new(10, 20);
+    let complex_float = num::complex::Complex::new(10.1, 20.1);
+
+    println!("Complex integer: {}", complex_integer);
+    println!("Complex float: {}", complex_float);
+}
+```
+
+### 复数相加
+复数计算和 Rust 基本类型的计算并无区别。
+
+```rust,editable
+fn main() {
+    let complex_num1 = num::complex::Complex::new(10.0, 20.0); // Must use floats
+    let complex_num2 = num::complex::Complex::new(3.1, -4.2);
+
+    let sum = complex_num1 + complex_num2;
+
+    println!("Sum: {}", sum);
+}
+```
+
+### 数学函数
+在 [num::complex::Complex](https://autumnai.github.io/cuticula/num/complex/struct.Complex.html) 中定义了一些内置的数学函数，可用于对复数进行数学运算。
+
+```rust,editable
+use std::f64::consts::PI;
+use num::complex::Complex;
+
+fn main() {
+    let x = Complex::new(0.0, 2.0*PI);
+
+    println!("e^(2i * pi) = {}", x.exp()); // =~1
+}
+```
