It is my\nfirst gem, so there's a *very* good chance I did something wrong, or did something \nnot-so-right. \n\nNumbers have always been a passion of mine, so this servers as a simple educational tool.\nGenerating numbers is fun, seeing various properties of the numbers you just generated is\neven cooler.\n\n## LICENSE\n\nInclude license information here.","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjdan%2Foeis","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fjdan%2Foeis","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjdan%2Foeis/lists"}
