logₓy

[cdmackay]

I apologise to those who prefer the other ordering/labelling

I don't think I gave it much thought, but my naive thinking involved seeing e.g. log₂ as the function, and I normally use x to denote the input of f(), leaving y as the base.

but I quite see the alternative, especially when you consider it as a function with two arguments, which of course it is.

thanks!

PS and I would normally write x-to-the-y, but it's often y-to-the-x on calculators.
