decimal [ID:746] (5/14)

in series: Python Beginners - Common Variables and Containers

(Showmedo is undergoing major changes. To report any problems viewing the videos please email us and include browser and OS specifics. Cheers - Kyran.)

The decimal type lets us store decimal data (like a float) without any precision problems (unlike a float!). This type is great for dealing with money or when you're concerned with fixed-precision accuracy.

It defaults to 28 decimal places, you can set that to any limit. You probably won't use it very frequently but it is great to know that a non-lossy alternative to the float type exists. If you've ever worked with rounding errors in C then you'll know how much of a time-sink these problems can be!

this is going to be a good resource in the future I am sure. Thanks for giving it special attention.


Another good overview of topic; decimal type. Short and to the point, with external link...


I really like how you explain where these names/syntax come from. It makes things so much easier to understand quickly and, importantly, REMEMBER. Thanks


Although I have some experience with Python, there are always tidbits of useful information even at the introductry level. Haven't used Python in quite a while so this is a good refresher.


Nice, clear introduction. Thanks.


great, thanks!


As you say, I probably won't use Decimal but it is good to know that it is there.

Educating the Open-source Community With Showmedo

Although as important as the software it supports, education and documentation are relatively neglected in the Open-source world. Coders love to code, and explaining how best to use or improve the software tends to be deferred or even sidelined.

At Showmedo we believe the community can play a vital role here and also say thanks for the tools and software that make our lives easier. If you have a piece of software you love or a programming langugage you are enthusiastic about, why not make a screencast showing others how to use it? All the stuff you wish you'd been told, the tips, tricks, insights that would have saved you time and frustration.

Screencasting is easier than you think, and we're happy to help you. You can emailus for advice or just use some of the how-to screencasts on the site. This screencasting learning-pathis a good place to start.

Kudos and Thanks for Ian
