Generally good cleanup @rgiulietti.
I'd like to see some kind of representation of the grammar of strings being
recognized included in this file, for example a cut-and-paste of the grammar
from Double.valueOf(String) (with leading and trailing spaces):
FloatValue:
Sign_opt NaN
Sign_opt Infinity
Sign_opt FloatingPointLiteral
Sign_opt HexFloatingPointLiteral
SignedInteger
HexFloatingPointLiteral:
HexSignificand BinaryExponent FloatTypeSuffixopt
HexSignificand:
HexNumeral
HexNumeral .
0x HexDigitsopt . HexDigits
0X HexDigitsopt . HexDigits
BinaryExponent:
BinaryExponentIndicator SignedInteger
BinaryExponentIndicator:
p
P
