A bit of a tangent, but could someone tell me if I'm wrong about the following: Arabic being read right to left while digit significance increases right to left means they use little-endian (although it looks like they say numbers in a middle-endian fashion like in German). This means users of left to right scripts made a mistake by not reversing the digits when copying the system.
What I can't find quickly is whether the Indian system where this originated wrote numbers in a big-endian or little-endian fashion. As far as I can tell, Indian languages are mostly written left to right, so should the first people to use the system with a right to left script have reversed the direction of digits?
