- Visible assumptions, field guidance, and an authoritative learning reference
Use boundary
Choose the maximum decimal places shown. This does not increase source accuracy.
Events follow a memoryless exponential model with a constant positive rate.
Use internally consistent units and retain extra precision when carrying the result into another calculation.
