Validation Error
A numeric string is expected, but the input provided failed the validation.
Explanation:
In programming, when a “numeric string” is expected, it means that the input should be a string (a sequence of characters) that represents a valid numeric value. This value can be an integer or a decimal number.
Examples of valid numeric strings:
- “12345”
- “3.14”
- “-42”
Examples of invalid numeric strings:
- “abc123”
- “12a34”
- “3.14.15”
