1.2.1. Half Arithmetic Constants
[Half Precision Intrinsics]
To use these constants, include the header file cuda_fp16.h in your program.
Defines
- #define CUDART_INF_FP16
- Defines floating-point positive infinity value for the half data type.
- #define CUDART_MAX_NORMAL_FP16
- Defines a maximum representable value for the half data type.
- #define CUDART_MIN_DENORM_FP16
- Defines a minimum representable (denormalized) value for the half data type.
- #define CUDART_NAN_FP16
- Defines canonical NaN value for the half data type.
- #define CUDART_NEG_ZERO_FP16
- Defines a negative zero value for the half data type.
- #define CUDART_ONE_FP16
- Defines a value of 1.0 for the half data type.
