Rounding

[jones24621]

Hello. I have been trying to make this code round my output to the nearest tenth of a digit for the Russel 2000 e-mini. I.e. - 78118 would be 781.20 or 78120. Any ideas? Thanks...


//==rnd will round to N digits.
function rnd(value, N) {
var n;
var mult=1;
for(n=0;n<N;n++) mult*=100;
value*=mult;
return Math.round( value,N)/mult;
}

Hi jones,


Try this...

//==rnd will round to N digits.
function rnd(value, N) {
    N=Number('1e'+N);
    return Math.round(value*N)/N;
}

rounding...

Steve:

Thanks for the quick reply. I tried that but it didn't work either. Gave me the same result. Russell e-mini prices still showed up as 81132 instead of 81130...Is there any other way to do this?

Thanks

Hi Jones,

Your welcome, sorry I missed the point. There is nothing in efs that will change the digit formatting of the chart that I am aware of. (if this is what you want)

I did a quick check using the search tool in the forum and found this link which may be of some help

A function to simply divide the number such that it is this format in your code is as follows

//==div will divide to N digits.
function div(value, N) {
    N=Number('1e'+N);
    return value/N;
} 

If you are trying to round the last digit of the number for your code, simply modify the rnd function I posted to reverse the order of multiplying and dividing.

Try this,

I also use the AB #F and just simply use Math.round....
after it rounds, then divide by ten outside the ()

Math.round(B2*10)/10

hope that helps
