Ruby Data Types

Data type is a way to notifying the operating system about the types of data a variable is going to hold through out it s code journey for example if we mention data as integer like a 1 it means we are notifying system that variable a is going to hold numeric value and in that case system will allocate appropriate space in the same way if we writing a.

Ruby data types.

Ruby data types. Assigning the value determines the data type. The program lists classes that belong to ruby data types. This is the boolean nature of our existence.

Ruby has 8 primary data types and 3 more data types derived from the numeric superclass. Ruby uses dynamic typing which means type checking is done at runtime rather than compile time as in languages that use static typing. In ruby you don t explicitly declare a data type before you assign a value. Ruby determines the data type from the data stored in the variable.

Data types are types of things that are mainly used to represent data such as numbers text and other values. As mentioned in the previous chapter everything in ruby is an object. There is a heaven and earth water and fire jing and jang man and woman love and hatred. There is a duality built in our world.

We will discusss the following data types.
