Remarks
Note: Half is not fast enought and precision is also very bad, so is should not be used for mathematical computation (use Single instead). The main advantage of Half type is lower memory cost: two bytes per number. Half is typically used in graphical applications. Note: All functions, where is used conversion half->float/float->half, are approx. ten times slower than float->double/double->float, i.e. ~3ns on 2GHz CPU.
