WebJan 2, 2015 · When a logarithm is taken, the number of decimal digits written after the decimal point -- is to be the same as the number of significant figures of the original number. As an example of the 'rule' in action: log10 ( 1.433e10 ) = 10.1562. Hence a 4 s.f. domain -- became a six s.f. range, (as written) a clear violation of the 'rule' you know.
