Small Calculator Hub

What it does

Small Calculator Hub offers fast, free online calculators for math, finance, health, and everyday needs. Calculate loans, taxes, BMI, and more instantly in one place.

Online calculators for math, finance, and health — plus 100+ tools for conversions, PDFs, and more. No sign-up, no downloads.

This is a browser-based online calculator that handles everyday arithmetic (addition, subtraction, multiplication, division) plus a set of scientific functions: square root, square, sine, cosine, tangent, and percentage. Everything runs instantly in your browser using JavaScript — nothing you type is sent to a server or stored anywhere, so it works even if your connection is slow. Tap the number and operator buttons the same way you would on a physical calculator, then press = to see the result. For example, entering 45 + 30 and pressing = returns 75 . The C button clears the whole entry, and the backspace button (⌫) removes the last character if you make a typing mistake. Square root (√):…from smallcalculatorhub.com

When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it. Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it.
