How this tool handles your input
String-based decimal movement preserves significant input digits while normalizing leading and trailing zeroes. Choose scientific or expanded decimal output.
Exponents are limited to ±10,000 for output safety. This does not track measurement uncertainty or meaningful trailing zero precision.
Example: 12300 → 1.23e4; 1.23e-3 → 0.00123
