value stored in the attribute. These methods are implemented within this
package.
- add($value)
- Adds the current value of the attribute to
$value.
- sub($value)
- Subtracts $value from the current value of the
attribute.
- mul($value)
- Multiplies the current value of the attribute by
$value.
- div($value)
- Divides the current value of the attribute by
$value.
- mod($value)
- Returns the current value of the attribute modulo
$value.
