Overview
NumericLimits is a tool class used to query attributes such as the maximum and minimum values of a specified data type.
The data type is specified by the template parameter T. The prototype definition is as follows:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 | template <typename T> struct NumericLimits { // Scalar API, which returns a scalar. constexpr __aicore__ static inline T Max(); constexpr __aicore__ static inline T Lowest(); constexpr __aicore__ static inline T Min(); constexpr __aicore__ static inline T Infinity(); constexpr __aicore__ static inline T NegativeInfinity(); constexpr __aicore__ static inline T QuietNaN(); constexpr __aicore__ static inline T SignalingNaN(); constexpr __aicore__ static inline T DeNormMin(); // Assign values to the first count elements of dstLocal. __aicore__ static inline void Max(const LocalTensor<T> &dstLocal, uint32_t count); __aicore__ static inline void Lowest(const LocalTensor<T> &dstLocal, uint32_t count); __aicore__ static inline void Min(const LocalTensor<T> &dstLocal, uint32_t count); __aicore__ static inline void Infinity(const LocalTensor<T> &dstLocal, uint32_t count); __aicore__ static inline void NegativeInfinity(const LocalTensor<T> &dstLocal, uint32_t count); __aicore__ static inline void QuietNaN(const LocalTensor<T> &dstLocal, uint32_t count); __aicore__ static inline void SignalingNaN(const LocalTensor<T> &dstLocal, uint32_t count); __aicore__ static inline void DeNormMin(const LocalTensor<T> &dstLocal, uint32_t count); }; |
