Float handling has gone away?

[skx]

Somewhere along the way we lost the ability to parse floats:

  10 DUMP 0.3
  20 PRINT "OK\n"

Output is:

  NUMBER: 0.000000
  Error running program: Token not handled: {IDENT .}

Yup, it's not the interpreter that is to blame, but the lexer:

   frodo ~/go/src/github.com/skx/gobasic $ ./gobasic -lex ./t.bas 
   {NEWLINE N}
   {LINENO 10}
   {IDENT DUMP}
   {INT 0}
   {IDENT .}
   {INT 3}
   {NEWLINE N}
   {LINENO 20}
   {PRINT PRINT}
   {STRING OK
   }
   {NEWLINE N}
   {NEWLINE N}

. is showing up as an IDENT which is just wrong ..

Better now :)

   frodo ~/go/src/github.com/skx/gobasic $ go build . ; ./gobasic -lex ./t.bas 
   {NEWLINE N}
   {LINENO 10}
   {IDENT DUMP}
   {INT 0.3}
   {NEWLINE N}
   {LINENO 20}
   {PRINT PRINT}
   {STRING OK
   }
   {NEWLINE N}
   {NEWLINE N}
