PrecisionBridge: COBOL-Java Numeric Consistency Engine

Migrating legacy COBOL to Java often produces subtle rounding bugs because COBOL’s fixed-point arithmetic is not preserved by Java’s floating-point types. PrecisionBridge automatically maps COBOL numeric fields to Java BigDecimal, validates arithmetic parity, and flags mismatches so that teams can correct precision errors before deployment.

Comment on: AI migrated legacy COBOL programs to Java, bugs included

COBOL is renowed for its fixed no rounding maths, utterly rigid and defined in the code, Java on the other hand is not (e.g., 0.1 + 0.2 becomes 0.30000000000000004), unless they are extensivly using BigDecimal, then its
