How to Check the Data Type of a Variable in Ruby

What is Ruby?

The Ruby programming language is free and open source. It is both object-oriented and interpretive. Yukihiro Matsumoto invented Ruby. Ruby’s founder referred to it as the jewel of programming languages because it was named after a gemstone. Here, we’ll talk about the various Ruby commands.

The following criteria were taken into account during the development of Ruby:

  • Simplicity
  • Extensiveness
  • Completeness
  • Portability

Most UNIX-based platforms support Ruby. Ruby was primarily developed on Linux. Common platforms like Windows, DOS, macOS, etc., are all compatible with Ruby.

1. Check integer datatype in Ruby

employees = {'Ahmad' => 9500, 'Irfan' => 6700, 'Ali' => 9700}
array=[1,2,3,4,5];
puts 1.class

2. Check float datatype in Ruby

employees = {'Ahmad' => 9500, 'Irfan' => 6700, 'Ali' => 9700}
array=[1,2,3,4,5];
puts 1.0.class

3. Check string datatype in Ruby

employees = {'Ahmad' => 9500, 'Irfan' => 6700, 'Ali' => 9700}
array=[1,2,3,4,5];
puts  'str'.class

4. Check boolean variable datatype in Ruby

employees = {'Ahmad' => 9500, 'Irfan' => 6700, 'Ali' => 9700}
array=[1,2,3,4,5];
puts false.class
puts true.class

5. Check Hash datatype in Ruby

employees = {'Ahmad' => 9500, 'Irfan' => 6700, 'Ali' => 9700}
array=[1,2,3,4,5];
puts employees.class

6. Check Array datatype in Ruby

employees = {'Ahmad' => 9500, 'Irfan' => 6700, 'Ali' => 9700}
array=[1,2,3,4,5];
puts array.class
