What is My-calculator? My-calculator is a powerful free online scientific calculator that works without installation, and is compatible with phones, tablets and computers.
Features My-calculator has the following features:
Lightweight, ultra-fast and works offline.
It not only saves displayed numbers, but also retains all other settings even after powering off and restarting. You can even continue previous calculation sequences after restarting.
Supports full keyboard input.
You can copy/paste content from the display using Ctrl+C (double-clicking also works for copying) and Ctrl+V.
Dynamic font size adjustment to keep numbers as clear and readable as possible.
It follows real scientific calculator operation rules, so 1+23=7 (…not 9 like other calculators), and 1(2+3)=5, 5²=25 (…not 8 like other calculators).
Theoretically supports unlimited parentheses.
You don't need to close parentheses if there is an equals sign after the equation.
