[Tutor] rounding up to the nearest penny

[Timothy Wilson]

Hi everyone,

I gave my students a programmig assignment (see
http://www.isd197.org/sibley/cs/icp/assignments/loancalc_html for
specifics) and discovered one small feature that I couldn't figure out (at
least easily).

My impression is that when doing financial calculations dollar amounts are
often rounded up to the nearest penny. The round function does a true
round to the nearest penny. The ceil function doesn't appear to work with
floats.

>>>
>>> amount = 1.342
>>> round(amount, 2)
1.34
>>> import math
>>> math.ceil(amount)
2.0

Any suggestions?

-Tim
