DecimalImpUtil_IntelDfp::ValueType128
uint64ToDecimal128(unsigned long long value);Description
Return a Decimal128 object having the value closest to the specified value subject to the conversion rules as defined by IEEE‐754:
* If value is zero then initialize this object to a zero with an unspecified sign and an unspecified exponent. * Otherwise if value has a value that is not exactly representable using std::numeric_limits<Decimal128>::max_digit decimal digits then return value rounded according to the rounding direction. * Otherwise initialize this object to value.
The exponent 0 (quantum 1e‐33) is preferred during conversion unless it would cause unnecessary loss of precision.
Return Value
closest 128‐bit decimal representation of value
