HalfFloat

The half precision floating point type.

The only operations are:

explicit conversion of float to HalfFloat
implicit conversion of HalfFloat to float

It operates in an analogous manner to shorts, which are converted to ints before performing any operations, and explicitly cast back to shorts. The half float is considered essentially a storage type, not a computation type.

struct HalfFloat {

static HalfFloat min_normal();

static HalfFloat max();

static HalfFloat nan();

static HalfFloat infinity();

static HalfFloat epsilon();

}

Bugs

The only rounding mode currently supported is Round To Nearest. The exceptions OVERFLOW, UNDERFLOW and INEXACT are not thrown.

Examples

HalfFloat h = hf!27.2f;
HalfFloat j = cast(HalfFloat)( hf!3.5f + hf!5 );
HalfFloat f = HalfFloat(0.0f);
