Numeric types include integers and floating point. Use the decimal module for fixed-point arithmetic when working with financial applications.
- [Instructor] Python 3 has two basic numeric types,…integer and floating point.…There are other types derived from these including the…built in complex type.…In fact, because everything is an object in Python,…you can derive your own types.…Here we're going to talk about integer and float.…Here in Komodo, I've opened a working copy of types.py…from chapter three of the exercise files.…And you notice down here on line four,…x equals seven, and seven is an integer.…
So if I save this and run it you see it says class int.…And if I multiply this by three,…save and run,…we now have a value of 21 and it's still a class int.…So it's an integer.…On the other hand if I say seven point zero.…And save and run it,…we now have class float, which is a floating point number.…Or, if I say seven times…three point one four one five nine,…I save this and run it,…we now have a floating point value because we used a…floating point number in our calculation.…
On the other hand, if I divide two integers,…say seven divided by three,…when I save and run this, I have a floating point number…
