Hello, 


I must handle numbers with high decimal precision due to the type of data I am measuring.


When doing the exercise of saving the number 744123812.85936641353 it shows me 744,123,812.85936677456 and 744123812.85936653614 is stored in the data bd. I don't understand what I'm doing wrong.


Could you give me a hand?

num= fields.Float('Number', digits=(21,11))

Hi Gustavo:

This is a standard issue with floating point arithmetic in python. Here's a link to a description of the issue and how to code to handle it.
