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. By the same token certain data types can only store numbers of a certain size.ĭescription. For example, if you try to fit twelve cans of soup in a box designed to hold ten cans, two cans will “overflow” that space. What this means is that a certain data type used for storing a piece of data was not large enough to hold the data. Make sure that numbers used in calculations that are coerced into integers do not have results larger than integers. The “Overflow” error means that you are trying to put a number into a variable (or property etc), and the data type of the variable doesn’t allow numbers that large. But knowing our data type actually helps.
Also, we have CLNG function for long data types to help us. We need to identify the variable and rectify it. When we encounter overflow error in VBA that means any one of our variables, not more is having some values which it cannot hold. For example, in VBA there is the Byte data-type, which can hold numbers one-byte in size - that is a number from 0 to 255. In VBA (as in most programming languages) a numeric overflow error occurs when you attempt to store a value in a variable that exceeds the maximum value that the variable’s data-type can hold. The most common reason is numbers that (for some reason) become formatted as dates… However, you are normally aware if you are dealing with such big numbers. So if you have numbers in trillions this could cause the problem. The overflow error in Excel PowerQuery is when the ‘number’ Excel sees is too big to handle.
