half

#include <Imath/half.h>

half is a 16-bit floating point number. See Floating Point Representation for an explanation of the representation.

See C-language half-float Conversion for C-language functions for conversion between half and float. Also, see Build-time half-float Conversion Configuration Options for information about building Imath with support for the F16C SSE instruction set.

Example:

#include <Imath/half.h>
#include <math.h>

void
half_example ()
{
    half  a (3.5);
    float b (a + sqrt (a));
    a += b;
    b += a;
    b = a + 7;
}
