...f a parser that has to support recursion, and in this case, spends lots of CPU building trees for structures you don't care about. (If someone wrote a finite state transducer that did proper (depth-limited) JSON parsing, that would be fantastic! In the meantime we have "grep -o".)

A computer uses binary, and in binary, there isn't any numbers like 0.1, but a mere binary approximation for that. Why? For the same reason than 1/3 cannot be written in decimal: its value is 0.33333333... w...
