Thanks, Larry. I'll add the (PRAGMA??) -DSQLITE_ENABLE_MATH_FUNCTIONS=1 to my compile and link, as well. I used to download the amalgamation from https://www.sqlite.com/download.html, unpack, and compile and link, and then copy to /usr/local/bin/sqlite3. Now, I do a 'fossil pull' into my clone of sqlite, followed by: ./configure make I'll get there. Linux is easy, for me.
