has() + get() with exception vs. get() + nullable result

I’m trying to calculate bearing degrees for a couple of coordinates using this formula: =DEGREES(ATAN2(COS(RADIANS(latA))*SIN(RADIANS(latB))-SIN(RADIANS(latA))*COS(RADIANS(latB))*COS(RADIANS(lonB-lonA)),SIN(RADIANS(lonB-lonA))*COS(RADIANS(latB)))) Set 1 LatA LongA LatB LongB 39.099912 […]
