Many thanks for your reply, Wolfgang. The issue is in Lua itself: print(5+"5") In versions prior to 5.3, result is "10".
From version 5.3, result is "10.0",
I would say this might be a bug. According to the “Lua 5.3 Reference Manual" (https://www.lua.org/manual/5.3/manual.html#3.1): A numeric constant with a radix point or an exponent denotes a float; otherwise, if its value fits in an integer, it denotes an integer. Well, "10.0" contains the radix point, but with no arithmetical relevance. My background is in humanities and I don’t understand the exponent for being a float ("10²" contains an exponent [https://www.m-w.com/dictionary/exponent], but I would say is an integer in all possible worlds [or all the worlds I know ]). Could anyone explain me what am I missing here or confirm whether this is a bug? Many thanks for your help, Pablo -- http://www.ousia.tk
