Concept80 位扩展精度 / 扩展精度格式
80-bit Extended Precision
A floating-point representation format comprising a 1-bit sign field, a 15-bit exponent field, and a 64-bit significand field including an explicit integer bit. It provides a wider exponent range and greater significand precision than single and double precision.
