I have been learning JavaScript in odd and made this function in POS. It works great, but I want to set the decimal precision to the result number so it only has two decimals.

I've searched a lot and tried different things but none worked for me.

I hope someone have an answer for this.

Example: 

1 / 3 = ‭0.3333333333333333‬    I want the result to be only    0.33

2 / 3 = ‭0.6666666666666667‬     I want the result to be only    0.67

This is the code:

test: function()( 

if (this. bigger){return(this. quantity*3)}

if (this. smaller){return(this. quantity/3)}

return this.  quantity
