**decimalDigits**- Return the number of decimal digits of precision for a FloatD. Technically, if P is the precision for the representation, then the decimal precision Q is the maximum number of decimal digits such that any floating point number with Q base 10 digits can be rounded to a floating point number with P base 2 digits and back again, without change to the Q decimal digits.
**emax**- Return the maximum allowable exponent for a FloatD that is finite.
**emin**- Return the maximum allowable exponent for a FloatD that is finite.
**fmax**- Return the largest normalized FloatD that is not infinite.
**fminNormalized**- Return the smallest normalized FloatD that is > 0
**infinity**- Return a FloatD that represents positive infinity.
**nan**- Return a FloatD that represents a mathematically indeterminate value (e.g. Inf - Inf, Inf / Inf).
**negativeInfinity**- Return a FloatD that represents negative infinity.
**precision**- Answer the number of bits in the mantissa. 1 + (2^-precision) = 1
