Since Xojo is restyling the coding syntaxes to more human and readable code, at least that was the intention, I should also expect some more human operation such as a runtime error when a divide by zero occurs. I remember a there was a scientific approach to have it behaving as it does, but despite…

This may help: [image] Xojo divides by ZERO? General Xojo is not a language that has ever raised an exception for divide by 0. Docs say: If you divide by zero, the result is positive or negative infinity, except if the numerator is also zero. In that case, the result is …

i think if a cake is not cut the cake stay original so a=12/0 i would expect 12. createing a runtime error for everything is not a good approach. that was the reason i wrapped every ms vb6 method into own one. i used methods that return a boolean if they done the task, so you can control the ap…

If there was some kind of runtime property that allowed the current functionality to be maintained then I guess it would be no problem allowing exceptions to be raised if the user wanted them. If Xojo just changed functionality then it would be another backwards compatibility killer.

I don’t see how. It would just expose code that already isn’t working properly, no?

It would expose code which isn’t handling it but would break code which is handling it.

If code is handling it, it won’t divide by zero, so it won’t see any exception. Or do you mean something else?

Yes, checking the result afterwards.

[image] MarkusR: a=12/0 i would expect 12. n/0 is not possible, so the result is undefined, it’s not a number. Undefined can’t be expressed as an integer number and that’s why typed languages (besides Xojo) raises an exception when someone tries it. Float types can carry some special values,…

let me explain different. xojo could made optional settings how xojo behave, to make the developer happy. see VB6 =Val(“Hello”) result in 0 see .net =Val(“Hello”) result in error (very unhandy) without error handling the app runs awhile and then it ■■■■■■ up. (at wrong input)

How? There’s no safe form without an Exception during the math expression failing. The result silently transferred to an integer as possible real value (and probably kind of random) can’t be compared and assured being result of an invalid math operation. It just can make silent mess to those who don…
