REXX NUMERIC DIGITS and NUMERIC FUZZ precision and comparison behavior across implementations

REXX arithmetic precision is governed by NUMERIC DIGITS and equality tolerance by NUMERIC FUZZ. The documented feature is implementation sensitive, with default values and comparison semantics varying between IBM z/OS REXX, Regina, and ooRexx. The goal is to establish a consistent understanding of how significant digit limits and fuzz tolerance affect numeri
