Why do SciPy stats return very small but very high precision numbers?

Sometimes, I see results like this:
LeveneResult(statistic=1233.9270599281986, pvalue=6.212186164025708e-269)
Is it even realistic to claim a value that is this small? (6.212 e-269)?
Other times, a function just returns 0.0.
Can someone point me to an explanation of how and why the functions decide o return 0 ("fer sure") vs "almost but not exactly 0, but close enough")
