Global Constant for Default Error Bounds

[hongyuchen1030]

Describe the feature you'd like added to this project
We require a universal constant to account for error tolerance in our project. Users will be able to define this constant, but if they do not specify a value, a default value of approximately 1.0e-15 will be used.

Additional context
This feature would be useful for ensuring consistency and accuracy in our project. It would also make it easier for users to customize their experience.

This has already been implemented, presumably as part of some of the other functionality you implemented.
