Gregory's ServerEXIF image metadata has the craziest way to store lat/lon coordinates that I've ever seen... a sequence of 3 (degrees, minutes, seconds) values stored as rational64u numeric types

@kgjenkins ffmpeg also uses something similar for framerate, but it makes a lot of sense there. Here... I do not know why. Maybe the people that did it hated IEEE 754? Just kidding. I bet they try to avoid precisión issues when converting to text, but this is only a random guess.   |
I've never heard of "rational64u" data types before -- was this something invented just for EXIF?
