in python, how do i split a number by the decimal point

So if I run:

a = b / c

and get the result 1.2234

How do i separate it so that I have:

a = 1
b = 0.2234

>>> from math import modf
>>> b,a = modf(1.2234)
>>> print ('a = %f and b = %f'%(a,b))
a = 1.000000 and b = 0.223400
>>> b,a = modf(-1.2234)
>>> print ('a = %f and b = %f'%(a,b))
a = -1.000000 and b = -0.223400
