Root bracket decision record
StatMedAnalysis | 14 November 2026

Document continuity, signs and stopping tolerance for a root search.
Check continuity on the bracket. Record endpoint values and the units of the x tolerance. Preserve the final interval, not only the rounded root.
Use synthetic or aggregate values only. Duplicate the blank row for additional records.

Function/version | Domain | Lower/sign | Upper/sign | Tolerance | Final bracket | Convergence
________ | ________ | ________ | ________ | ________ | ________ | ________

Fictional example: For x squared minus 2, values at 1 and 2 are -1 and 2; the positive root is about 1.414214.
