rounding off numbers

[coaxc...@gmail.com]

Good day all

I have been out of the game for a while. My question is say, i have a number 25.345678 and i just want to return 25.345, what command would i use?

function OnStart()

{

   lay=app.CreateLayout("linear", "VCenter, FillXY")

   txt=app.AddText(lay, "Hello")

   app.AddLayout(lay)

   

   num = 25.345678

   //to round it to 25.346

   r = num.toFixed( 3 )

   //to truncate it to 24.345

   t=(Math.floor(num*1000)/1000).toFixed( 3 )

   app.Quit( r + "\n" + t). // display both

Hi,

This looks like a javascript question.

Normally 25.345678 would round up to 25.346

The obvious answer is to multiply by 1000 ( 25345.678 ), then round ( 25346 ), then divide by 1000 (  25.346 )

var x =  25.345678  ;

var y = x * 1000 ;

var z = Math.round(y) ;

Alert (z / 1000) ;

If you just want to chop the extra decimal places then use Math.floor(y) instead of Math.round(y)

Regards, ah
