Anyone have a quick back-of-the-envelope function for finding main
sequence initial stellar mass?

Say a function where x is some number from 1 to infinity (or for
practical purposes finite number around a million or so) and the
function would return a solar mass with a vertical asymptote at 200
solar masses? (Using the Salpeter value would be fine for a BOTE
function I would think.)

I can't seem to beat the math for that out of my brain. It’s been
eluding me for the better part of a week.

I'm working on a game and I'm trying to get a realistic spread of
solar masses for the stars. (My drawing routine already does a fair
job of turning out a star with the appropriate color and radius (well,
the radius is not accurate, I had to reduce the apparent radius of the
O, B, and A class stars because they were just too big for the map,
and I haven’t even added red giants and super-giants yet) but getting
an accurate spread of masses is giving me trouble.

There would also be a "metallicity" effect. The greater the
metallicity, the smaller the stars, and vice -versa- A. McIntire
