How to replace NULL% by 0%

Issue

In my calculatePercents () method, I should get 0% instead of NULL%.

In my console.log, I get prints with the values NULL

 calculatePercents() {
    this.v.global.total.amount = this.v.global.cash.amount + this.v.global.sec.amount;
    console.log("Cash => " + JSON.stringify(this.v.global.total.amount));
    console.log('------------------------');
    this.v.global.cash.percent = (this.v.global.cash.amount / (this.v.global.cash.amount + this.v.global.sec.amount)) * 100;
    console.log(" Global cash " + JSON.stringify(this.v.global.cash.percent));

    this.v.global.sec.percent = (this.v.global.sec.amount / (this.v.global.cash.amount + this.v.global.sec.amount)) * 100;
    console.log(" NULL ???? ==> " + JSON.stringify(this.v.global.sec.percent));

    var totPercent = (this.v.global.cash.percent + this.v.global.sec.percent);

    this.v.global.total.percent = totPercent;

}

How I could get a 0 instead of NULL please.

Solution

you can use || operator to set zero

Eg:

this.v.global.total.percent = (totPercent||0);
