Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

number-transform-roman

一个用于数字转换成罗马数字的 class 类,你可以使用 transformRoman 来进行数字转换罗马数字,也可以使用 calculation 来进行计算再转罗马数字.


引入
import * as ntr from 'number-transform-roman'  // ntr 为 number-transform-roman 简写
使用方法
transformRoman

transformRoman(type: number | string ) 数字转换罗马数字

    import * as ntr from 'number-transform-roman'
    
    // 数字类型
    new ntr().transformRoman(990108010)  // 结果为:CMXC#,C#VIII,#X#

    // 或者

    // 字符串类型
    new ntr().transformRoman('80108010')  // 结果为:LXXX#,C#VIII,#X#
calculation

calculation(type: function ) 数字计算表达式

    import * as ntr from 'number-transform-roman'
    
    // 参数为匿名函数表达式
    new ntr().calculation(() => 2 * 6 / 3)  // 结果为:IV

    // 注意:如果匿名函数加了 {} ,请加 return 语句

    // 加了 {return xxx}
    new ntr().calculation(() => {return 2 * 6 / 3})  // 结果为:IV

罗马数字里的0

罗马数字里没有 0,所以在此使用 # 来代替,避免计算时得出的结果包含 0

后续可以进行splice,自行去转换

罗马数字的位数

因为罗马数字里最大只有千位符 (M) ,所以在此进行了千位分隔符,返回的数据将呈现为 xxx,xxx,xxx
