BIGINT field is string in getterMethods

I have the next model:

var Sequelize = require('sequelize');

module.exports = function () {
    return {
        attributes: {
            uuid            : Sequelize.STRING,
            ccc    : {type: Sequelize.BIGINT, allowNull: false},
            vvv   : Sequelize.BIGINT,
            bbb  : Sequelize.BIGINT
        },
        options: {
            getterMethods: {
                outstandingBalance: function() {
                    var ccc = this.ccc ? this.ccc : 0,
                        vvv = this.vvv ? this.vvv : 0,
                        bbb = this.bbb ? this.bbb : 0;

// the same if I do this.getDataValue('vvv') , I receive string as well

                    console.log(ccc, vvv, bbb);

                    return (ccc + vvv - bbb);
                }
            },
            classMethods: {},
            instanceMethods: {

            },
            tableName: 'xxx_calc'
        }
    };
};

Which produces the next to the console:

The values are strings for some reason, however, if I would completely receive the model and print the value from the resolve method, the value of the ccc, vvv and bbb would be number.

I mean here:

YYY.find({ /* where */
                }).then(function (yyy) {
                    console.log(yyy.uuu.vvv);

                    return reply(yyy);
                });

Could you tell me how can I receive the number values in the getterMethods as well? Is that normal behaviour?

It seems it’s strings all around in the example you posted? Which is as it should be, since bigint can’t reliably be stored in javascript ints, right? Accessing properties directly or with get also returns strings

Look into bignumber support in node myslq in you want numbers: https://github.com/felixge/node-mysql/#connection-options, in connection with dialectOptions http://docs.sequelizejs.com/en/latest/api/sequelize/#new-sequelizedatabase-usernamenull-passwordnull-options
