Random Number Generator

How a whole number is chosen

Generate reads the current Minimum and Maximum, cuts each with Math.trunc, and if the low value is above the high value it exchanges them. The span is high minus low plus 1, so both ends are included. A single 32-bit value from crypto.getRandomValues is divided by 2^32, and the integer is low plus the floor of that fraction times the span. Count tells how many independent draws to print. They are joined with newlines and nothing else. There is no header, no comma, and no index.

Equal bounds produce a column of that same integer, once per count. A span of 1 through 6 can repeat a face. The page never switches to sampling without replacement. If you already have the names and you want their order shuffled, that is the list shuffler, which reorders lines you paste. This page invents integers. It will not take the list 1 through 6 and permute it.

Minimum, maximum, and count

The three boxes are labeled Minimum, Maximum, and Count (1-500). Only Count is rewritten when Generate clamps it. Minimum and Maximum stay as typed even when the draw used them swapped or truncated. Type 10 in Minimum and 1 in Maximum, and a count of 5 still prints five integers from 1 through 10. The boxes continue to show 10 and 1. Type 3.9 and the draw uses 3. Type -1.2 and the draw uses -1, because truncation is toward zero, not toward the next lower integer.

A huge magnitude is still a JavaScript number. Past the safe integer range the bound you typed may already be imprecise before the draw starts. The page does not warn about that, and it does not switch to big-integer arithmetic. Count never exceeds 500 and never drops below 1 on a click. Editing Count to 0 leaves 0 in the box until Generate, which then stores 1 and prints one line.

Jobs for a batch of integers

Use a count of 1 when you need a single id suffix or a single die. Use a larger count when a spreadsheet needs a column of sample ages, scores, or ports inside a known span. Copy output after Generate is the lines you see, suitable to paste under a header you add yourself. The number formatter can add grouping separators afterward. This page will not insert thousands separators or currency symbols.

Letters, digits, and symbols in one token are the random string generator. It draws one string of a chosen length and does not accept a numeric minimum. A UUID is a different shape again. Nothing on this page sorts the column, drops duplicates, or forces each integer to appear once.

The hint line and a fresh visit

Before the first Generate, the panel reads No output yet. Range will use 1 to 100. when the boxes are still at their defaults, or the swapped-and-truncated bounds if you already edited them. That sentence is only the panel placeholder. Copy output still says there is nothing to copy, because the published result is an empty string until Generate runs. After a click, the panel and the copy buffer are the same newline-separated integers.

The boxes and the last column are component state for this visit. They are not written to local storage by this tool. A reload restores Minimum 1, Maximum 100, Count 1, and the hint sentence. The previous column is gone. There is no seed field, so you cannot ask for the same column twice. Two clicks with the same bounds are two draws.

Rules and limitations

Each output line is an integer from the inclusive low bound through the inclusive high bound. Bounds are truncated toward zero and swapped when Minimum is greater than Maximum. Count is clamped to 1 through 500 on Generate.

Duplicates are kept. Decimals are not printed. There is no uniqueness switch, no seed, no download, and no local-storage restore. The pre-click hint is not the copy buffer.

Common problems

If the numbers ignore the order you typed, Minimum was above Maximum and the draw swapped them. The boxes still show the typed order.

If you expected 500 distinct values, this page can repeat. It draws with replacement. Use a shuffle of a list you wrote when each line must appear once.
