Hi B,

You should read these:

https://floating-point-gui.de/

https://www.volkerschatz.com/science/float.html

https://randomascii.wordpress.com/category/floating-point/

https://docs.oracle.com/cd/E19957-01/806-3568/ncg_goldberg.html

There's a lot of information to digest, but until you understand it, you 
can't understand why numeric calculations behave as they do, or tell the 
difference between a bug and an unavoidable result.
