Yeah, that's coming from floating point representation.
In [9]: 1234.56
Out[13]: 1234.5599999999999

but you can easily amend the n2w string to fix this for you:

In [11]: def correct_cents(num,s):
   ....:     s = s[:s.index("point")]
   ....:     s += "and %d/100" % int(num*100%100)
   ....:     return s
   ....: 


In [12]: correct_cents(1234.56,'one thousand, two hundred and thirty-four point five five')
Out[12]: 'one thousand, two hundred and thirty-four and 56/100'

Here's my 56 character code-golf version of the above:

In [12]: c=lambda n,s:s[:s.find("p")]+"and %d/100"%int(n*100%100)
In [13]: c(1234.56,'one thousand, two hundred and thirty-four point five five')
Out[13]: 'one thousand, two hundred and thirty-four and 56/100'

best,
