Is there any buil-in function to return the lesser of two numbers?

i.e. lesser(100,125) would return 100.

Do I need to roll my own?

Which is it--greatest or least?

No matter, TFM has something to say about it:

I found GREATEST() and LEAST(), which in combination with COALESCE()
returns exactly what I needed. I missed it because I was looking for
numerical functions. Like so many other things in life, in retrospect,
it's completely obvious.
