What is accurate rendering of the expression "invalid at computed-value time"?

Question

I tried to render the expression "invalid at computed-value time" into very understandable Russian as "недопустимое значение", and so trimmed in a way that retains no real essentials. I really don't want to say "invalid value".

Let me explain... this is a computing term. For example, I have a function, an input value and a conditional statement that defines if an output value returned by the function is acceptable. I don't know if the input value is valid to be taken as an input because it depends on what the output value is. Later, at computation time, the output — the computed value — proves to be unacceptable, so the input value is invalid at computed-value time.

What would be the accurate rendering of the expression, so that it never needs to be explained in order to be properly understood?

Answer 1

I would approach it similarly to a stable expression:

"Invalid run-time value" which translates to "Недопустимое значение во время выполнения."

If we need to differentiate compute-time from run-time, we can translate:

"Invalid at computed-value time" as "Недопустимое значение во время вычисления."

In my opinion, the literal translation is "Недопустимо во время вычисления значения." But that phrase (adverbial clause) is less convenient for usage in different contexts.

Answer 2

I'd like to propose a translation based on your description. You said that a certain value being used as an input parameter leads to an unacceptable result. So, in Russian it would be something like this:

Значение переменной [which you use as input] приводит к неприемлемому результату

P. S. As a programmer, I prefer clear error explanations. Error text has to explain a situation as much as possible, so it's more of an explanation than a translation.

Answer 3

Folant,

If I understood your task correctly, you're dealing with a function and a conditional statement that evaluates these function outputs. In this case, your function + the conditional statement is basically another function that has its own range and domain. For this reason, if an output value isn't acceptable, I'd simply say: "The input parameter is out of the range" and, by definition, that automatically means that the corresponding output value isn't acceptable in a process of computation. A Russian equivalent for "The input parameter is out of the range" is "Входной параметер вне области определения", and this message sounds scientific and elegant in Russian.

Answer 4

"Недопустимое значение" seems to be totally fine for what you described. I don't see any problem. If you want to explain the reason for this value being invalid, you can explain it briefly, like "Недопустимое значение: (the condition that makes it invalid goes here)".

Unfortunately, I don't see any real way of going with no explanation at all in your case, unless you explain it somewhere else, which, in turn, isn't going without an explanation. :)

Answer 5

Если по завершении вычислений выясняется, что входное значение недопустимо… Входное значение, чья недопустимость выясняется по завершении вычислений… — В таких случаях бывает полезно переводить описательно.

То есть значение, которое всегда было недопустимым (в математическом смысле: функция на этом значении не определена), но о котором можно это выяснить только по окончании вычислений — по проверочному условию, наложенному на вычисленное выходное значение.

I get the impression that you came up with terminology that was difficult to understand even in English.

Answer 6

In mathematics, the problem of finding the input value from the output is called "the inverse problem". So what you're describing is a check of whether a certain input value produces an output value residing in a certain subset of the codomain of your function.

In Russian, you can express your point like this:

значение аргумента, приводящее к результату, лежащему за пределами желаемой области значений, - и в этом смысле неприемлемое

Answer 7

Входное значение недопустимо

You don't have to render a complete sentence, as many answers suggest. Just focus on the primary relationship between things.

The difference is that the English message doesn't talk about input, which is, in my opinion, confusing, while focusing on the obscure compute-time term, which is redundant — of course you need to evaluate in order to figure out whether input is correct is not. But in a case where you also need to signal statically invalid input:

Входное значение вне диапазона

Note that having a proper verb isn't necessary in Russian.
