A monkey patch for boto's Decimal context to allow inexact and rounded representation of floats. Used to store any float in DynamoDB when inexactitude is allowed.
Raw
boto_decimal_monkeypatch.py
# 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

Thank you for this.

I couldn't find a general and meaningful representation for my floating numbers that didn't cause issues, some I just patched things like you said.
