# Monkey patch Decimal's default Context to allow 
# inexact and rounded representation of floats
import decimal
from boto.dynamodb.types import DYNAMODB_CONTEXT
# Inhibit Inexact Exceptions
DYNAMODB_CONTEXT.traps[decimal.Inexact] = 0
# Inhibit Rounded Exceptions
DYNAMODB_CONTEXT.traps[decimal.Rounded] = 0
