WebWhen the exponent is of the half-float is 31 (the number represents either Infinity or NaN), the resulting float number must have an exponent value of 255. When the exponent of the half-float is zero and the mantissa is non-zero, the number is a subnormal half-float. These values can be represented as normalized float by adjusting WebMar 4, 1990 · 67 // We want to use the __half_raw struct from the HIP header file only during the device compile phase.
