How to resolve the algorithm Literals/Floating point step by step in the Julia programming language

Table of Contents

Problem Statement

Programming languages have different ways of expressing floating-point literals.

Show how floating-point literals can be expressed in your language: decimal or other bases, exponential notation, and any other special features. You may want to include a regular expression or BNF/ABNF/EBNF defining allowable formats for your language.

Let's start with the solution:

Step by Step solution about How to resolve the algorithm Literals/Floating point step by step in the Julia programming language

The provided Julia code demonstrates different ways to represent numeric literals in the language:

  1. 0.1: This is a decimal floating-point number. The decimal point indicates that the number is less than 1.

  2. .1: This is also a decimal floating-point number, but the leading zero is omitted. It is equivalent to 0.1.

  3. 1.: This is a floating-point number without a fractional part. The decimal point is required to distinguish it from an integer.

  4. 1e-1: This is a floating-point number in scientific notation. It represents 1 multiplied by 10 raised to the power of -1, which is equal to 0.1.

  5. 1e+10: This is also a floating-point number in scientific notation. It represents 1 multiplied by 10 raised to the power of 10, which is equal to 10 billion.

  6. 1e-10: This is a floating-point number in scientific notation. It represents 1 multiplied by 10 raised to the power of -10, which is equal to 0.0000000001.

  7. 0x01p-1: This is a hexadecimal floating-point number. The "0x" prefix indicates that the number is in hexadecimal (base 16), and the "p-1" suffix indicates that the number is multiplied by 2 raised to the power of -1, which is equal to 0.5.

These examples showcase the various ways to represent numeric values in Julia, allowing you to choose the notation that best suits your specific needs.
