/**
 * Provides parsers that parse a {@code FloatingPointLiteral} from a
 * {@link java.lang.CharSequence}, {@code char} array, or {@code byte} array
 * ({@code str});.
 * 
 * Leading and trailing whitespace characters in {@code str} are ignored.
 * Whitespace is removed as if by the {@link java.lang.String#trim()} method;
 * that is, characters in the range [U+0000,U+0020].
 * 

 * The rest of {@code str} should constitute a  {@code FloatingPointLiteral} as described
 * by the lexical syntax rules shown below:
 * 

 * 
 * FloatingPointLiteral:
 * [Sign] {@code NaN}
 * [Sign] {@code Infinity}
 * [Sign] DecimalFloatingPointLiteral
 * [Sign] HexFloatingPointLiteral
 * SignedInteger
 *

 * 
 * HexFloatingPointLiteral:
