Yep. 4 decimals is plenty for every application and as you said, just multiply it by a million if not. I was more addressing the issue that on some online forums people tend to think finance needs specialized 2 decimal software. Only a fraction of finance does. Most others just use the usual IEEE 754 specification that is standard in modern programming languages and OSes for their daily use. Heck, excel uses IEEE 754 for most cases and like 95% of finance runs on excel.
