Point flottant 16 bits Numpy

# to create an x-bit point with numpy, use np.intx
# to create an unsigned x-bit point with numpy, use np.uintx
# examples:
import numpy as np

a = np.int16(10000) # 10000 stored as a 16-bit number (can store numbers from -32768 to 32767)
b = np.uint(10000) # 10000 stored as an unsigned 16-bit number (can store numbers from 0 to 65535)
