string.find problem

[ertlflorian1]

Why it everytime outputs for a and e 1?

addCommandHandler ("mi", function (player, cmd, wert) 
zahl =  tostring (wert) 
outputChatBox (zahl) 
a , e = string.find (zahl, ".") 
outputChatBox ("a:"..a.." e:"..e) 
end) 

Example:

Ingame /mi 41.1

then

a: 2 e: 3

Unless specified otherwise, string.find uses patterns rather than plain strings. Dot is one of the special characters and it means any character. You either have to disable the pattern matching

a , e = string.find (zahl, ".", 1, true) 

Or escape the magic character

a , e = string.find (zahl, "%.")
