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'.
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?
Oh damn it. $$anonymous$$y bad, thanks. I will update my post.
Use parseInt() to convert an enum to its integer value.
