[Tutor] Unexpected result from decimal

[Jacob S.]

Hi all,
   I'm having a problem that is ticking me off. (to put it lightly)
Why does decimal do this --  I thought that getcontext().prec was number of 
decimal places?

import decimal
decimal.getcontext().prec = 2
a = decimal.Decimal(2)
b = decimal.Decimal(3)
100*a/b
Decimal("67")
print 100*a/b
67

Why does it do this?
It's really, really, messing things up for me because results are not 
interpreted in my programs correctly.
Jacob
