Re: Calculation gives wrong result

As Jon mentioned, RPG and COBOL have the same exact precedence rules...
https://www.ibm.com/docs/en/i/7.5?topic=arithmetic-expressions

For that matter every language I've heard of has the same precedence rules,
since precedence was defined long before computers came to be.
Division and multiplication have the same precedence and are thus evaluated
left to right.

Jon's other post about COBOL defaulting to ResDecPos explains why it might
seem as if COBOL has different precedence rules.

In COBOL, the precedence of math operators is PEDMAS:
*() ** / * + -*

In RPG, multiplication and division have equal precedence, so the first
encountered is the first executed

Both of these should give 4:
7 * (4 / 7)
7 * 4 / 7

RPG gives 3 and 4 as the result. I assume it has something to do with
intermediate result variables, but I can't see how. Can someone explain?
