lg is ambiguous notation that requires further clarification, since it has been used inconsistently across the boarder literature. lg as the binary logarithm seems to be popular across computer science literature, but lg as the base-10 logarithm is quite common in mathematics literature (particularly German and Russian literature, where this is the standard meaning). In fact, there are international standards (ISO 31-11 and ISO 80000-2) and a German national standard (DIN 1302) that define the abbreviation lg to mean the base-10 logarithm. Of course, NIST also recommends following the ISO standards (see


It’s especially satisfying when it is both linguistic and mathematical pedantry at the same.

I just have to do my part to help keep these ratios up…
