Cool; how is the book?

Those functions and variables should be defined in the 'math' module, so
you may need to 'import' the math module before playing with it.  Here's
an example in the interactive interpreter:

###
>>> import math
>>> math.pi
3.1415926535897931
>>> math.ceil(math.pi)
4.0
>>> math.floor(math.pi)
3.0
