About Bengawan 4D

Bengawan 4D is a free-to-use web tool built around one idea: a 4-digit number contains more information than it first appears to, and that information can be shown clearly with basic mathematics.

Enter a number such as 4827 and the site breaks it down into its individual digits, their sum, how many are odd or even, which digits repeat, and how the digits are distributed. Enter a list of numbers and it summarises them together with frequency counts, averages and distributions.

The site is designed for anyone who wants a quick, reliable 4D number analysis tool: students practising number properties, people who work with numeric codes or records, and anyone curious about the arithmetic behind a set of 4-digit numbers.

What the 4D Number Analyzer does

The 4D Number Statistics & Analyzer works in two modes.

• Single number analysis. A full breakdown of one 4-digit number: its digits, digit sum, odd and even digits, highest and lowest digit, repeated digits, a 0–9 frequency chart and simple properties such as whether it is a palindrome or divisible by 3.

• Multiple number analysis. Paste up to 2,000 numbers and get 4D number statistics across the whole list: digit frequency, most and least frequent digits, average digit sum, odd/even distribution, how many numbers contain repeated digits, and a detailed table for every entry.

Every result describes the numbers you entered. The tool reports what is there; it does not suggest what should come next.

How our calculations work

Each 4-digit number is treated as a string of four digits, so leading zeros are kept (0528 is analyzed as 0, 5, 2 and 8). From there, every figure comes from straightforward arithmetic and counting:

• Digit sum adds the four digits. Digital root keeps adding until one digit remains.

• Odd and even checks each digit’s remainder when divided by 2. Zero counts as even.

• Frequency counts how many times each digit from 0 to 9 appears, overall and by position.

• List statistics use standard formulas: mean, median, minimum, maximum, range and population standard deviation.

Features

Everything the 4 digit number analyzer offers, in one place:

• Digit frequency

  Counts for every digit 0–9, shown as a bar chart.

• Digit sum

  The sum of the four digits, plus averages across a list.

• Odd & even analysis

  The odd/even split per number and across all numbers.

• Repeated digit detection

  A clear yes or no, with how many times each digit repeats.

• Highest & lowest digit

  The largest and smallest digit and the range between them.

• Pattern breakdown

  Pattern type, palindromes, digit order and divisibility.

• Number statistics

  Mean, median, range, duplicates and position frequency.

• Copy and reset

  Copy results as plain text, or clear everything in one click.

Our approach to accuracy

Because every result is based on whole-number arithmetic and counting, the same input always gives the same output. There is no randomness, estimation or hidden weighting in any calculation.

We keep the methods simple on purpose, so that you can verify any figure yourself with pen and paper. Where a result depends on a definition, such as zero being even or a “pair” meaning exactly two matching digits, the tool states that definition next to the result.

Inputs are checked before anything is calculated. Entries that are not exactly four digits are flagged and listed, rather than silently dropped or corrected, so the statistics only ever include the numbers you intended.

Privacy-friendly usage

The analyzer does its calculations directly in your web browser using JavaScript. The numbers you type or paste into the tool are not sent to a server to be processed, and you don’t need an account, email address or any personal details to use it.

When you close or reset the page, your entries are cleared. If you want to keep your results, use the Copy Results button and save them wherever you like.

What the tool does NOT do

Bengawan 4D is a calculator for 4-digit numbers. To be completely clear about its limits:

In an independent random draw, every combination from 0000 to 9999 has exactly the same probability. A digit that appears often in a list is no more likely to appear next time, and a digit that has not appeared is not “due”. Frequencies and patterns describe past input only.
