What happen when numbers are entered in text data type field?

When numbers are entered into a text data type field, they are treated as strings rather than numerical values. This means that any mathematical operations or comparisons involving these numbers will not function as expected, since the text representation can lead to concatenation instead of arithmetic calculations. Additionally, if validation rules are in place, the system may reject the input if it expects a different data type. Overall, the handling of numeric input in text fields can lead to errors or unexpected behavior in data processing.
