Set Decimal Places

CS Discoveries Coding and Debugging Help

Hi-

Working an ATM app in CSD Projects. Using the setNumber tool to display dollar amount in a label, however it drops the zeroes in the display i.e. 100.00 displays as 100.

Is there a way to control the number of decimal places to display?

you should be able to by using the .toFixed prototype, assuming the structure your using is a Number and not a String here’s how you would do that

var num = 100;
console.log(num.toFixed(2));

the 2 represents how many additional places you wish to see after the decimal spot hope this helps
