How to resolve the algorithm Literals/Integer step by step in the Picat programming language

Table of Contents

Problem Statement

Some programming languages have ways of expressing integer literals in bases other than the normal base ten.

Show how integer literals can be expressed in as many bases as your language allows.

Note:   this should not involve the calling of any functions/methods, but should be interpreted by the compiler or interpreter as an integer written to a given base. Also show any other ways of expressing literals, e.g. for different types of integers.

Let's start with the solution:

Source code in the picat programming language

% All outputs are in base 10
main =>
  println(100),                                % plain integer
  println(1_234_567_890),                      % underscores can be used for clarity
  println(1_000_000_000_070_000_030_000_001),  % arbitrary precision
  nl,

  println(0x10ABC),                            % Hexadecimal
  println(0xBe_ad_ed_83),                      % lower or upper case are the same
  nl,
  
  println(0o666),                              % Octal
  println(0o555_666_777),
  nl,

  println(0b1111111111111),                    % binary
  println(0b1011_1111_1110)
