Python3 compatibility: math error compatibility

The way math is handled with typing is completely different in python3.

% python2<<EOF
x=10
y=8
print((x + (y - 1)) / y * y)
EOF
16

python3<<EOF
x=10
y=8
print((x + (y - 1)) / y * y)
EOF
17.0

So we need to force an integer for the round function as follows and
maintain compatibility with python2.

python3<<EOF
x=10
y=8
print(int((x + (y - 1)) / y) * y)
EOF
16
