One common type of range error is when a value is outside the range of values that a particular data type can represent. For example, an integer can only store values between -2147483648 and 2147483647. If a value outside this range is stored in an integer variable, it will result in a range error.
A different type of range error can occur when a calculation results in a value outside the range of values that the data type can represent. For example, if an integer variable is divided by 0, it will result in a range error.
