Difference between decimal, float and double in .NET?
...n a decimal form, and expect exact results in decimal representations; not all decimal numbers are exactly representable in binary floating point – 0.1, for example – so if you use a binary floating point value you'll actually get an approximation to 0.1. You'll still get approximations when usi...
Creating an empty list in Python
...
However, in practice, this initialization is most likely an extremely small part of your program, so worrying about this is probably wrong-headed.
