soundPressureLevel() intermittently returns 'inf' at low levels on AVR

[PaintYourDragon]

In the dm-mic-spl fork, running the soundPressureLevel example. Open serial monitor (not the plotter) and (when quiet) you'll see some "inf"s mixed in with the numeric output. Only happens on AVR; ARM seems unaffected. @dhalbert

Wrong button. Sorry! :)

oh oops I had fixed this yesterday but must have messed up with git. It should have been doing it with both AVR and ARM, just ARM is a bit lower of a floor.
should be fixed here: 69e7237

It's a bit too loud to test right now at the factory but I'll plug it in when I get home.
