Javascript Tutorial - 22 - Basic Math Objects

[xray5632]

@B1KMusic intresting well im too used to vb so that is why i use wired syntax here any way in vb best way to randomize a number is to creat an object of the "random" class and with that randomize a varible so its like (if you know vb): Dim a As Integer  Dim b As New Random a = b.Next(1, 200)

and 1 is the lower number

and 200 is the higher number

so that is why i love vb its good for making programs that you need to make fast for practical uses

[xray5632]

var num1 = (Math.random())

if (num1<= 1) alert ("number is not int");

[iAckeh]

Okay, whole numbers can't. You must have meant integers.

What if you want the randomly generated number to be an integer? Do you have to generate a random fraction and then round it? Or is there a simpler way?

Also, how can you specify that you want it to be a certain length or certain number of decimal places?

[heyawhaw]

the nuber of Math.random() is always a decimal number between 0 and +1. To have a number between 0 and +1000 you multiply it. Let's say you want it in a variable

var num1 = Math.random()*1000

To get rid of the excess decimal you can now round them off:

var num1 = Math.round(Math.random()*1000)

and to make this a decimal number between 0 and +10 you just divide it by 100

var num1 = Math.round(Math.random()*1000)­/100
