Like other such CUDA intrinsics starting with a double underscore, __float2half () is a device function that cannot be used in host code. Since host-side conversion from float (fp32) to half (fp16) is desired, it would make sense to check the host compiler documentation for support.

WebThis is a decimal to binary floating-point converter. It will convert a decimal number to its nearest single-precision and double-precision IEEE 754 binary floating-point number, using round-half-to-even rounding (the default IEEE rounding mode). It is implemented with arbitrary-precision arithmetic, so its conversions are correctly rounded. Webfloat_half_convertion Half is a compact data type used in machine learning. This is a simple program demostrating the convertion between half and float data type.
