In Windows, a stack overflow error can be caused by certain types of malware. In programming, the call stack is a buffer that stores requests that need to be handled.

What does stack overflow mean in computer terms?Ī stack overflow is an undesirable condition in which a particular computer program tries to use more memory space than the call stack has available.

Increase Thread Stack Size (-Xss) There might be legitimate reason where a threads stack size needs to be increased.

Because of a non-terminating recursive call (as shown in the above example), threads stack size can grow to a large size. There are couple of strategies to address StackOverflowError.

If we want to allow values larger than 2147483647 (or smaller than -2147483648), we can simply use the long data type or a BigInteger instead. Handling Underflow and Overflow of Integer Data Types This type of error is somewhat common in programming, especially when dealing with integers or other numerical types of variables.Ĥ. In computing, an overflow error is an error that happens when a program receives a number, value or variable outside the scope of its ability to handle. Overflow errors occur when the execution of a set of instructions return a value outside of this range. All computers have a predefined range of values they can represent or store. In computing, an overflow error can occur when a calculation is run but the computer is unable to store the answer correctly. What happens when there is an overflow error?

Instead, we must write CLng(200)*300 - or use the implicit type Long constant 200& and/or 300&, which can be confusing. The same thing happens if we write CLng(200*300). In your case, the problem arises because the expression i*y is evaluated as type Integer, before it is converted to type Long to be stored into j.

More importantly, using type Single can lead to incorrect values when the variables are converted to type Double for example, storing into an Excel cell.Īnd as you learned, using type Integer can lead to 'premature' overflows. And even that is debatable, considering the huge main memories, cache lines and secondary storage in modern computers. But that should matter only with humongous arrays. The only benefit might be in memory space. In modern computers, there is no performance benefit to using type Integer and type Single. In fact, in general, always use type Long for integer variables and type Double for non-integer variables. Solution is to declare i and y type Long.
