in reply to [OT] Mysterious function. (Updated)

My _guess_ is that it's working out where to put the graduations when drawing a graph.

i.e. when the graphed interval is 1 year put tick marks every 1 month, 2 years - ticks every 2 months, .. 500 years - ticks every 50 years. There is some obvious repetition -- you could scale some of the results, as the answer for (100 - 1000) is ten times as big as that for (10 - 100). HTH

    Thank you! Now you've pointed it out, it makes a lot of sense in isolation.

    In the actual example it appears to be called for all three axis, only one of which is date related.

    But then there is some conditional code that is rather opaque; so it might be that it is only used by the months axis.
