Priotizaer: Prime Factorization-er

Priotizaer

How to Use

  • Type the input (positive integer) then hit 🏃‍♂️‍➡️ Run button or press Enter/Return on keyboard.
  • Minimum input value is 1, and maximum of 9,007,199,254,740,991.
  • Modify the input value to clear the result.
  • To abort a certain computation, simply modify the input, delete a number or add another number.

Output

  • Priotizaer will show the prime factorisation and factor multiplication list of the input number (if the input can be factorised).
  • If the input is a prime number, Priotizaer will return the Prime word.
  • For non-integer or negative number or value beyond limit, Priotizaer will show error message.
  • Priotizaer will also show the time spent for the process to finish (in milliseconds) at the bottom of the output.
  • We can copy the prime factorisation or a factor multiplication row by clicking/tapping it.

The Limit

  1. Because of the iterative ♻️ technique.

    This actually has already been solved. 🥳

    Priotizaer is updated to:
    • Implement the Web Worker API. So that your computer's fans would howl like bunch of banshees after three spoons of guacamole. Take that, non-fan Apple contraption.
    • Run on the latest cleaned flow and logic.

    Therefore, it should go smoother than its initial version. ✅

  2. JavaScript limitation Number.MAX_SAFE_INTEGER = 9,007,199,254,740,991 (64‐bit IEEE 754 standard).

    9,007,199,254,740,991 is nine quadrillion seven trillion one hundred and ninety-nine billion two hundred and fifty-four million seven hundred and forty thousand nine hundred and ninety-one, thank you.

Use Priotizaer as Your Reference

Priotizaer can directly calculate the number using URL parameter ➡️ ?number=YOUR_NUMBER.

As such:

https://portraptor.johanpaul.net/2015/09/priotizaer-prime-factorization-er.html?number=20

Example, in anchor tag:

<a 
    href="https://portraptor.johanpaul.net/2015/09/priotizaer-prime-factorization-er.html?number=20"
    target="_blank"
    rel="noopener"
    title="Open new tab">
    Prime factorisation of 20
</a>

The URL template is like so:

https://portraptor.johanpaul.net/2015/09/priotizaer-prime-factorization-er.html?number=YOUR_NUMBER

Template in anchor tag:

<a 
    href="https://portraptor.johanpaul.net/2015/09/priotizaer-prime-factorization-er.html?number=YOUR_NUMBER"
    target="_blank"
    rel="noopener"
    title="Open new tab">
    YOUR LINK TEXT
</a>

We can serve it as a link for the calculation of a particular number. 👍

Mind you, this is not an API. It's simply using (linking) this actual page — but with number as the query parameter. This post URL doesn't serve calculation through fetch — you'll certainly get a CORS error. 😂 Because, indeed, it's not meant for that.

✅ Checkmark UNICODE Regular Expression on Blogger

This part is quite a quirk on Blogger. I suppose it's from CodeMirror normalisation method (for rendering consistency). Blogger uses CodeMirror for their text editor.

Thus, here is a snippet to properly match this character ✅ on Blogger:

//  - "✅" (U+2705)
//  - "☑" (U+2611)
//  - "✓" (U+2713)
//  - "✔" (U+2714)
//  - plus an optional variation selector (U+FE0F)

/(?:\u2705|\u2611|\u2713|\u2714)\uFE0F?/

We can use the u (unicode) flag for that, optionally:

/(?:\u2705|\u2611|\u2713|\u2714)\uFE0F?/u
