よくある質問
2 件の質問
Q1Do large numbers lose precision?
No. Conversion runs on string long division, never through floating point, so 9007199254740993 comes out digit for digit. Tools built on parseInt quietly change the last few digits.
Q2Can I enter negative numbers?
Yes, and you get a minus sign in the result. Note that two's-complement forms like 0xFFFFFFFF depend on the bit width, which the tool will not guess for you.
