Complexnumbers for Rust. Usage Add this to yourCargo.toml: [dependencies]num-complex="0.4" Features This crate can be used without the standard library (#![no_std]) by disabling the defaultstdfeature. Use this inCargo.toml: [dependencies.num-complex]version="0.4"default-features=false ...

创建新工程cargo new complex-num && cd complex-num 在Cargo.toml中的[dependencies]下添加一行num = "0.4.0" 将src/main.rs文件中的main函数替换为下面的代码 运行cargo run use num::complex::Complex; fn main() { let a = Complex { re: 2.1, im: -1.2 }; let b = Complex::new(11.1, 22.2...
3、固定精度的十进制小数,常用于货币相关的场景。 好在社区已经开发出高质量的 Rust 数值库:num。 use num::complex::Complex; fn main() { let a = Complex { re: 2.1, im: -1.2 }; let b = Complex::new(11.1, 22.2); let result = a + b; println!("{} + {}i"...
use 关键字将 create 导入到当前文件范围,命名空间操作符(::)限制了包含的内容,只需要类型:Complex 类型不需要构造函数,使用类型名称(Complex)并在大括号 { } 内给它们的字段(re, im)赋值(2.1, -1.2)即可初始化类型 为了简化,许多语言的类型实现了 new()方法,Rust 语言没有这个约定 num::complex::Complex ...
而是通过散文（又称文档）表达的：Complex<T>是与阵列[T; 2]兼容的存储器布局。
use num::Complex;// ...use image::ColorType;use image::png::PNGEncoder; 并且Cargo.toml 文件中指定了我们想要的每个 crate 的版本: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 [dependencies]num="0.4"image="0.13"crossbeam="0.8"
[dependencies]image = "0.23.4"num-complex = "0.2.4" 修改源文件main.rs如下 extern crate image;extern crate num_complex; fn main() { let imgx = 800; let imgy = 800; let scalex = 3.0 / imgx as f32; let scaley = 3.0 / imgy as f32; ...
num = "0.4.1" crossbeam = "0.8" 完整代码: 编码实现 0. 创建项目 cargo new mandelbrotcdmandelbrot 1. 复数表示 使用复数,我们需要引入一个 crete:num: cargo add num 其中定义了一个复数类型Complex: pubstructComplex<T>{/// 复数的实部pubre:T,/// 复数的虚部pubim:T,} ...
fn main() {// default integer numeric type is i32let num1 = 123;println!("{} - type: {}", num1, get_type(&num1));// default floating point numeric type is f64let num2 = 1.23;println!("{} - type: {}", num2, get_type(&num2));// explicit typinglet num3: i8 = 23...
