Parameters:

x	A single-precision floating point value

Returns:

A half-precision floating point value

floatie_fp16 f16tof32()

Convers a half-precision floating point value to a single-precision floating point value.

Parameters:

x	A half-precision floating point value

Returns:

A single-precision floating point value

voidfloat \*const ie_fp16 \*size_tfloatfloat f16tof32Arrays(, , , , )
