To do a logarithm in a base other than 10 or e, we employ a property intrinsic to logarithms. From our first example above, log 2 (64) may be entered into a calculator as “log ...

How do you create logarithms? Creating logarithms starts with understanding basic formulas such as the following. log 2 16 = 4, because 2 4 = 2 × 2 × 2 × 2 = 16. ...

For more accuracy, do a polynomial fit (equivalent to what’s done in the article if you do a bit more trickery!). For instance, 15 is 1111. 3 shifts to the last 1, so integer part is 3.

Today’s commonly used base 10 logarithms were introduced in primitive form by Henry Briggs after Napier died in 1617. (Briggs acknowledged, though, that it was Napier’s idea to do so.) ...

Logarithms are a common idea today, even though we don’t use them as often as we used to. After all, one of the major uses of logarithms is to simplify computations, and computers do that jus… ...

Revise what logarithms are and how to use the 'log' buttons on a scientific calculator as part of Higher Maths.

Why do they need to do this? Because logarithmic scaling is the natural system for magnitudes of quantities in the sciences. That's why a new claim that logarithmic mapping of numbers is the ...

This post offers reasons for using logarithmic scales, also called log scales, on charts and graphs. It explains when logarithmic graphs with base 2 are preferred to logarithmic graphs with base 10.
