Best Way to Round Up Numbers Using Javascript

I previously found several solutions to round up (float) numbers to closest two decimal places. Some are using complicated function with sofisticated codes but I find this one-liner quite effective and efficient:

Math.round(num*100)/100; // for two decimal places
Math.round(num*1000)/1000; // for three decimal places

I appreciate the author who did this and sorry for forgetting where I get it from.
