Zeros after number in a whole number with the decimal shown are significant. Therefore these Trailing zeros when they are merely placeholders to indicate the scale of the number. Multiplication rounding and division rounding is performed based on the number of significant figures in the measurement with the lowest count of significant digits. Numbers can be rounded to a given number of significant figures, for example when the measurement device cannot produce accurate results to a given resolution. Often, leading zeroes or trailing zeroes can be removed and the number remains just as accurate (004 means the same as 4, for example). Significant Figures (Sig Fig) Rounding Calculator.
