Ruby Test Is Number - Ruby

Introduction

Ruby Test Is Number is a Ruby module that allows you to easily test if a given string is a number or not. This can be useful in situations where you need to validate user input or read input from a file.

The module works by exposing a test_is_number method that takes a string as an argument and returns a boolean value indicating whether or not the string is a number.

Installation

To install Ruby Test Is Number, simply run:

gem install test_is_number

Usage

To use Ruby Test Is Number in your code, simply require the module and call the test_is_number method with the string you want to test. Here's an example:

require 'test_is_number'

puts test_is_number('123')   # true
puts test_is_number('1.23')  # true
puts test_is_number('12a3')  # false
puts test_is_number('12 3')  # false
puts test_is_number('')      # false

As you can see, the test_is_number method returns true if the string is a number and false otherwise.
