Should round up to 0.03<

Answer 1

The python round function could be rounding the way not you expected.

You can be more specific about the rounding method by using Decimal.quantize

eg.

from decimal import Decimal, ROUND_HALF_UP
res = Decimal('0.25').quantize(Decimal('0.0'), rounding=ROUND_HALF_UP)
print(res) 
# prints 0.3
