WebFeb 14, 2016 · $\begingroup$ So how do you calculate logarithms with a slide rule? (No fair using the log scale or the loglog scales.) One way a slide rule can help is by providing accurate first approximations for the square roots that you need if you want to do the log by binary bracketing. A slide rule is also helpful in interpolating from a table. $\endgroup$ WebThe LOG function syntax has the following arguments: Number Required.
