Create a Decimal128 object having the value closest to the specified value following the conversion rules as defined by IEEE-754:

DecimalImpUtil::ValueType128
binaryToDecimal128(float value);
* If value is signaling NaN, store the value of the macro EDOM into errno and return signaling NaN value. * Otherwise if value is NaN, return a NaN. * Otherwise if value is infinity (positive or negative), then return an object equal to infinity with the same sign. * Otherwise if value is a zero value, then return an object equal to zero with the same sign. * Otherwise if value has an absolute value that is larger than std::numeric_limits<Decimal128>::max() then store the value of the macro ERANGE into errno and return infinity with the same sign as value. * Otherwise if value has an absolute value that is smaller than std::numeric_limits<Decimal128>::min() then store the value of the macro ERANGE into errno and return a zero with the same sign as value. * Otherwise if value needs more than std::numeric_limits<Decimal128>::max_digit significant decimal digits to represent then return the value rounded according to the rounding direction. * Otherwise return a Decimal128 object representing value.
