float('١٢٣٤.٥٦') 1234.56
I think it's a bug that this works. The definition of the float builtin says
Convert a string or a number to floating point. If the argument is a string, it must contain a possibly signed decimal or floating point number, possibly embedded in whitespace. The argument may also be '[+|-]nan' or '[+|-]inf'.
Now, one may wonder what precisely a "possibly signed floating point number" is, but most likely, this refers to
floatnumber ::= pointfloat | exponentfloat pointfloat ::= [intpart] fraction | intpart "." exponentfloat ::= (intpart | pointfloat) exponent intpart ::= digit+ fraction ::= "." digit+ exponent ::= ("e" | "E") ["+" | "-"] digit+ digit ::= "0"..."9"
Regards, Martin
