For debugging purposes, it would be helpful to include information in error messages about what caused a given error, and preferably, where it occurred. For example, instead of returning a message like:
Invalid number. Exponent indicator has to be followed by a digit.
It would be more informative to specify the position in the input where the invalid number is, and/or attach the number to the message.
