Random Number Generator

Draw uniform values between your bounds — integers use crypto.getRandomValues when available; decimals sample uniformly for quick simulations. Everything runs locally like APK Analyzer and APK String Extractor: no server round-trip. Compare with Fake Data Generator for full mock rows.

What this is for

Use this page for quick samples, dice rolls, classroom demos, and test data — the same client-side only trust model as APK String Extractor. It is not a certified lottery or cryptographic key generator.

Privacy

Numbers are never sent to DroidXP. Optional min, max, count, and mode may be saved in localStorage on your device.

How to use it

  1. Step 1: Choose Integer or Decimal, set min, max, and how many draws.
  2. Step 2: Click Generate (or a dice preset) and read the stats line.
  3. Step 3: Copy the lines into spreadsheets, scripts, or games.

Frequently Asked Questions

Does DroidXP send my min, max, or generated numbers to a server?

No. Random draws run only in your browser — the same local-only stance as APK Analyzer and APK String Extractor. Optional defaults may be saved in localStorage on your device only.

Are the numbers cryptographically secure?

Integers use crypto.getRandomValues when your browser supports it for unbiased uniform integers in the range; decimals still use Math-derived uniform floats. Do not rely on this page for secrets, keys, or high-stakes draws.

Are min and max inclusive?

Yes — both endpoints are possible outcomes for integers; decimals are sampled uniformly across the closed interval including the endpoints in practice within floating-point precision.

Why can decimal results look “uneven” in the last digit?

Floating-point math has finite precision — treat decimals as samples for demos, not exact rationals.

Can I use this for gambling or regulated lotteries?

No — this is a general-purpose helper for everyday sampling. Official games need certified RNG processes.

Is there a limit on how many numbers I can generate at once?

The UI caps batch size to keep the page responsive; extremely large batches may still feel slow on low-memory devices.

Can I set a seed to reproduce the same sequence?

This tool does not implement reproducible seeded streams — each run draws fresh values.

How is this different from the UUID Generator on DroidXP?

UUID Generator outputs formatted identifiers. This tool focuses on numeric ranges, batches, and quick dice-style presets.

Does it work offline?

After the page loads once, generation works offline because logic is client-side — similar to offline-friendly APK parsing.

What about accessibility?

Results appear in a plain text area you can select and copy; use your OS screen reader with the labeled form controls.
