how to use a value of enmu to do Mathematics operation with int type ? ( In Javascript )

help!! how to use a value of enmu to do Mathematics operation with int type ? ( In Javascript ) like:

enum aaa { ONE, TWO, Three}

var i = 5 ; var j = 6 ; var sum = i + j * aaa.TWO;

but it's wrong~

Error message is BCE0051: Operator '*' cannot be used with a left hand side of type 'int' and a right hand side of type 'aaa'.

Use parseInt() to convert an enum to its integer value.

Firstly, Enums start from 0, so calling it ONE will still yield 0 as it's value. To start your Enum incrementing from 1 you would have to define your Enum like so:

enum aaa
{
   ONE = 1,
   TWO,
   THREE
};

As for doing maths with them, you will need to cast it to an int like this:

EDIT: Corrected cast for JavaScript.

var sum = i + j * parseInt(aaa.TWO);

This will work for how you want to use it. Though I'm curious to ask why you're doing this?
