I'm looking at the Enterprise COBOL Performance Tuning paper regarding the ARITH(EXTEND) compiler option which says -
| *ARITH - EXTEND or COMPAT * | The ARITH compiler option allows you to control the maximum number of digits allowed for decimal | numbers (packed decimal, zoned decimal, and numeric-edited data items and numeric literals). With | ARITH(EXTEND), the maximum number of digits is 31; with ARITH(COMPAT), the maximum number | of digits is 18. However, ARITH(EXTEND) will cause some degradation in performance for all decimal | data types due to larger intermediate results. The amount of degradation that you experience depends directly | on the amount of decimal data that you use. | Performance considerations using ARITH: | On the average, ARITH(EXTEND) was 1% slower than ARITH(COMPAT), with a range of equiv- | alent to 38% slower. | (*COB PG: *pp 37, 41, 48-49, 95, 283-284, 557-566) Can anyone say what "with a range of equivalent to 38% slower" means. It doesn't make sense to me. I don't even think it's English.
