In Sage, 1/2 is the fraction 1/2 and so you do have : sage: 1/2 1/2 sage: 1/2+1/2 1 On the sage interface, integers are Sage Integers and not python int. But yes, if you write a .py file that you call with sage, then 1 is a python int and you have: sage: int(1)/int(2) 0 which is quite common for many programming languages as floats are quite a messy thing (which is not due to python, floats are messy everywhere). sage: 0.5+0.5==1.
