This change replaces library routine calls with GENERIC arithmetic for floating-point ADD and SUBTRACT operations in Cobol. This optimization aims to accelerate execution by performing calculations directly within the compiler’s intermediate representation. The update also includes minor fixes and new helper routines for floating-point conversion.
