String#split not working

[Hanumashin]

case#1
try
'12345678901234567890#123'.split('#')[0]
and get (wrong result)
'12345678901234567890#123'
but it should
'12345678901234567890'

case#2
try
'12345678901234567890#12'.split('#')[0]
and get (correct result)
'12345678901234567890'

Has anyone found this like me?
Please help.

Maybe I miss something but you split at the . and in your first example you compare with a string which stoll contains the . and bot parts but in the second example you compare to only the 0 element before the .

It seems this is absolute correcy but maybe I missunderstand something. can you explain what you would expect and why?

I cannot reproduce the issue. Could you show us an error reproducing script?

[bovi]

Oh i think I got what you mean. You are saying that you apply split with '.' but the result is still a string with a .? I can't reproduce this. Do you have additional code before this bug? What are your compiling option?
