```>    num = num + math.pi/6.0   ## Don't forget .0 or you'll get an integer

the division operator returns a float when either of the operands are
floats -- in this case math.pi is, so you don't have to worry about
passing it 6.0 instead of 6

>>> import math
>>> math.pi
3.1415926535897931
>>> math.pi / 6
0.52359877559829882

>>> type(math.pi)
<type 'float'>
>>> type(6)
<type 'int'>
>>> type(6.0)
<type 'float'>
