I just don't know where to use int or float, so, when in doubt I use float. Am I right?

Best ResponseYou've already chosen the best response.0int is for integer values when you know that you won't have decimal places. for example a counter for quantities that do need decimal precision (like money or distance) you should use float does that make sense?

Best ResponseYou've already chosen the best response.0"When in doubt, use float" has been exactly my strategy, though I do grasp the differences between them, as described by Chris.

Best ResponseYou've already chosen the best response.0You're pretty much right. Floats are basically scientific notation in binary. There are some values that they can't hit exactly. This can cause some interesting issues in comparison ( == ) statements.

Best ResponseYou've already chosen the best response.0ints are standard and should be used when in doubt. They are 1, 2, 3, etc. Int ranges up to 2 million I believe. Floats also know as "Singles" as 32 bit decimal numbers 1.0, 2.4, 2.3242343242342343, etc. Double's are 64bit floats.

Best ResponseYou've already chosen the best response.0If you are doing math operation it is good idea to use floats, but anywhere else it is better to use int.

Best ResponseYou've already chosen the best response.0float and int have a difference purposes. Float when you know for sure you will need it. For example lets say you have a variable you are going to use for a loop or comparision later in the program its better to use int and if needed a float value of that convert it.

Best ResponseYou've already chosen the best response.0Did you see lecture 2 video? Basically, BEWARE of using integers with division. With floats, 3.0 / 2.0 is 1.5. But 3/2 returns 1. As the lecturer pointed out, this is a trap for Python newbies because dividing one integer by another (like 3/2) is done with an integer result!

Best ResponseYou've already chosen the best response.0Remember that with Python 3.0 this dilemma is solved since it automatically uses float when a float could occur in the results. You can still override this by using e.g. `//` for integer (instead of float) division.

Best ResponseYou've already chosen the best response.0Int is an integer and float is a decimal. Right?
