how to add support for float16 type in array class

Question

Why does the C/Python array class does not support float16?

/ I can see that other projects like numba also dont have support float16/

Is there way to add support? if yes is it easy?

the reason i'm asking is because if an array is too big float32 takes twice the space. Having an option seem reasonable ! if not available there have to be some reason

It seems the intel, CPUs, does not support float16 ops naively. but support conversion..

lscpu | grep Flags | grep f16c

Answer 1

what do you mean its not supported etc?

a_float_16 = numpy.zeros(10, dtype=numpy.float16)
