Behind the result - No mystery in the method
The parser separates sign, written decimal digits and any e exponent. The first nonzero digit defines a normalized coefficient with magnitude at least 1 and less than 10. The exact decimal shift supplies the integer power of ten. In the reverse direction, the same value is expanded by shifting the decimal point and inserting zeros. Zero is displayed as 0 × 10^0 by convention. The number is kept as a reduced fraction of BigInt integers, not parsed as a binary floating-point number. This is value conversion: original trailing zeros are not retained as a measurement claim.

Before you go
Is the conversion exact?
Yes, for accepted finite decimal inputs within the displayed limits. Entered digits are treated as exact numeric values. If the original number was a rounded measurement, conversion cannot recover omitted digits or establish its physical accuracy.
How do I type a negative exponent?
Use e notation such as 6.02e-7, or enter the standard decimal directly. Do not type ×10, caret expressions, commas or units in the numeric field. A leading minus sign belongs to the value, not automatically to its exponent.
Why are my trailing zeros removed?
This tool converts the numeric value and normalizes the display. Use the Significant Figures tool when written zeros carry precision information. For zero, 0 × 10^0 is a convention, not a unique normalized form.
