Integers

Integers are positive or negative whole numbers that can be stored as a constant or variable. E.g. 3, 42, -39, etc. are integers while 3.2, -4.3, "abc", etc. are not integers. In this article we show how integers can be created and saved in various programming languages.

=Python 3: Integers= Integers are natively supported in Python. There is no distinction between constants and variables in Python, as everything is a variable by default. Type declaration is optional, although it is a good practice to state the variable typing using the native function  or the   type from the   package. Non-integer numbers can be converted to integers using the same native function.

Unlike other languages, Python 3 has only single integer type and it can support very large integer values.

$ python >>> from typing import Int >>> a = 3  # No type declaration >>> b: int = 5 # Type declaration using native int function >>> b: Int = 5 # Type declaration using Int from typing >>> c = int(5.3) # Converting non-integer to integer

=R: Integers= Integers are natively supported in R. It should be noted that, every number is a vector in R. Hence defining one integer is effectively defining a one dimensional vector in R. There is no distinction between constants and variables in R, as everything is a variable by default.
