Many thanks for your reply, Wolfgang.

The issue is in Lua itself:


In versions prior to 5.3, result is "10".

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

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,
