๐ก Comprehensive Guide to Web Calculator
1. Does this calculator support keyboard input?
Yes, fully supported! You can seamlessly use your keyboard. Numbers (0-9), operators (+, -, *, /), decimal point (.), and Enter (=) work natively. Use Escape to clear all and Backspace to delete the last entered digit.
2. How does the percentage (%) button work?
The % button instantly divides your current input by 100. This is exceptionally handy for calculating discounts or taxes. For instance, computing 15% of 200 is as simple as typing "200 ร 15 %" yielding 30.
3. Does it handle floating point precision errors?
Absolutely. Unlike many basic JavaScript calculators that will show "0.1 + 0.2 = 0.30000000000000004", this tool includes built-in precision correction to ensure your financial and decimal math remains 100% accurate without weird trailing digits.
