Python math module not able to calculate

Question

I am writing a little python script and have run into a problem.

Comma_shift = 503559669306.1
Simpdays = (Comma_shift - math.floor(Comma_shift))*10

This should give me 1, but it gives me 0 for Simpdays. If Comma_shift is equal to 503559669306.2 I get 2, as expected. What am I doing wrong? Is there some rounding involved that I am not aware of?

Thank you!

What's the output of `print(type(Comma_shift), repr(Comma_shift), Comma_shift.__sizeof__())`? — Kelly Bundy, Apr 23 '22 at 08:10

0

The value of Simpdays comes out to be 0.999755859375 so yes, I do think the value is being rounded.

Are you printing the value? – chomprrr Apr 23 '22 at 07:59
