## Demo
```
->>> import sfpy
->>> sfpy.Float32(1.3) + sfpy.Float32(1.4) # <-- construct from doubles
-Float32(2.6999998092651367)
->>> sfpy.Float32(3) # <-- construct from raw bits
-Float32(4.203895392974451e-45)
->>> sfpy.Float32(3).bits
-3
->>> x = sfpy.Float16(0)
->>> x
-Float16(0.0)
->>> x += sfpy.Float16(10.0) # <-- in-place operators have better performance
->>> x
-Float16(10.0)
->>> sfpy.Posit16(1.3) + sfpy.Posit16(1.4) # <-- posits work the same way as floats
-Posit16(2.7001953125)
->>> q = sfpy.Quire16(0) # <-- quire is also supported
->>> q
-Quire16(0.0)
->>> q.iqma(sfpy.Posit16(3), sfpy.Posit16(5))
->>> q
-Quire16(3.725290298461914e-09)
->>> q.iqma(sfpy.Posit16(3.0), sfpy.Posit16(5.0))
->>> q
-Quire16(15.0)
->>> q.bits
-1080863910568919232
->>> bin(q.bits)
-'0b111100000000000000000000000000000000000000000000000011000000'

-## Building (on Linux)
-The Cython module can be built in place in the usual way:
-
-`python setup.py build_ext --inplace`
-
-This requires the submodules to be checked out, and the static libraries `SoftPosit/build/Linux-x86_64-GCC/softposit.a` and `berkeley-softfloat-3/build/Linux-x86_64-GCC/softfloat.a` to be built. Note that in order for Cython to be able to build the shared objects for the module, the static libraries must be compiled with -fPIC, which currently requires modifying the appropriate Makefiles manually. SoftPosit can be build with -fPIC using its python2 and python3 targets.
-
-The package can also be installed to a local Python distribution with pip, i.e. `pip install .` from the top level of the repository using the appropriate pip. This requires that Cython be installed.
