DESCRIPTION¶
This trait provides native delegation methods for numbers. All of the operations
correspond to arithmetic operations like addition or multiplication.
DEFAULT TYPE¶
If you don't provide an "isa" value for your attribute, it will
default to "Num".
PROVIDED METHODS¶
All of these methods modify the attribute's value in place. All methods return
the new value.
- •
- 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.
- •
- abs
Sets the current value of the attribute to its absolute value.
BUGS¶
See "BUGS" in Moose for details on reporting bugs.
