Calculation path
The base-10 order of magnitude determines the normalized exponent; engineering notation rounds the exponent down to a multiple of three.
Calculation path
Coefficient = number / 10^exponent, where exponent = floor(log10(abs(number))).

Use boundary
Choose the maximum decimal places shown. This does not increase source accuracy.
Significant-digit formatting rounds the displayed coefficient but does not change the entered source value.
Results are educational math aids. Check notation, units, rounding, assumptions, and required precision before using an answer in graded, engineering, financial, or safety-critical work.
