Decimal vs float in Python. When working with decimal numbers in Python, we usually turn to floats. Floats serve us well for most purposes, such as simple divisions, but they do have limitations that can become incredibly problematic for certain use cases. They're simply not precise enough. However, floats aren't our only option, and today we ...Sep 21, 2012 · more useful information extracted from the cited book. numeric (precision, scale) = decimal (precision, scale) - Exact Numeric Data Types. real = float (24) - Approximate Numeric Data Types.
