Details

• Describe what you were trying to get done.

I had to convert floats to Decimal but somehow the current Double I got out of Decimal when looking at it using ToDouble would give me only the round part of the double. I figured that my floats were not native python but numpy float64 . This issue happens only with numpy floats..
