>>> import scalar
>>> print(scalar.foo.__doc__)
foo(a,b)

Wrapper for ``foo``.

Parameters
----------
a : input float
b : in/output rank-0 array(float,'d')
 
>>> scalar.foo(2, 3)   
     A=  2. B=  3.
 INCREMENT A AND B
 NEW A=  3. B=  4.
>>> import numpy
>>> a = numpy.array(2)   # these are integer rank-0 arrays
>>> b = numpy.array(3)
>>> scalar.foo(a, b)
     A=  2. B=  3.
 INCREMENT A AND B
 NEW A=  3. B=  4.
>>> print(a, b)          # note that only b is changed in situ
