Doable, but should it be required.  The Java Language specification 
section 3.10.2 gives the syntax for floating point literals.  I feel 
that the class StreamTokenizer should be fixed so numbers are recognized 
using this syntax, which does recognize scientific notation.

Read the definition of the class StreamTokenizer again.  The method 
parseNumbers is called one time to set a switch to recognize and convert 
number syntax into the equivalent double value.

Easier than this is to totally ignore the supposed capability of 
StreamTokenizer to recognize numbers, read each token as a String and 
perform the conversion outside the class StreamTokenizer.  But this 
raised the issue of why have the capability of recognizing numbers by 
StreamTokenizer if it is not usable.

Again, I feel that the class StreamTokenizer should be fixed so numbers 
are recognized using the syntax in section 3.10.2 which does recognize 
scientific notation.  How do I go about achieving this?
