sum values in vuejs2

Question

hi i have this vuejs2 code

    this.total = 0;
    console.log(this.total_without_discount);
    console.log(this.total_taxs);
    console.log(this.total_discount);
    this.total += this.total_without_discount;

    return Number(this.total).toFixed(this.comma);
},

now when i get the result back i gat Nan all these functions are in computed how can i sum the values inside totals function and return it back thanks

One of total_without_discount, total_taxs or total_discount returns either undefined or NaN. Without a proper minimal reproducible example we cannot tell you exactly what is going on besides: Make sure that they do not return that. — Sumurai8

Use parseInt or parseFloat, depending on the data type and precision needed:

totals() {
    this.total = 0;

    this.total += parseFloat(this.total_without_discount);
    this.total += parseFloat(this.total_taxs);
    this.total += parseFloat(this.total_discount);

    return parseFloat(this.total).toFixed(this.comma);
},
