Math Rounding & Abs Value

[buzybill]

I been trying to use rounding and Abs value for number variables. For some it's been giving me errow message. What am I doing wrong?

ex)

var aValue = 20;
var bValue = 21;

var myValue = aValue / bValue * 100; //Should be 95.238095238..

myValue = round(myValue); //should be 95

Thanks,

This line in your code
myValue = round(myValue);
should be written as follows
myValue = Math.round(myValue);

One more thing!

What function would I use if I want to have a number specific up to 3 decimal point

ex)

x = 15.333333333;
function -->
x = 15.333

Thanks,

You would use the .toFixed() method to define a specific number of decimals eg myVar = x.toFixed(3)

Not a number?

I guess after You use myVar = x.toFixed(3) it no longer a number, but string. Is that correct?

Thanks,

That is correct. The .toFixed() method converts a number to a string. You can however convert it back to a number by multiplying it by 1
