Parameters

Remarks

If String contains more than one number, then only the number closest to the end of the string is changed. For example, 'A10B20' is changed to 'A10B19' and 'a12b12c' to 'a12b11c'.
If String contains a negative number, then it is increased by one. For example, '-55' is changed to '-54'.
