int(Math.random()*200)+100

[farafiro]

Can any body tell me what this means ??
I might look silly but isn'r it useless unless u put a number between the () of the RANDOM ???

No, by default Math.random() returns a decimal between zero and 1. Multiplying it by 200 gives you a random number between 0 and 200, but it woudl still have decimal places, so they use Int() to round it. Then add 100.

Thanks Jesse
But wouldn't it be the same as If I wrote
(Math.random (200))+100
and no use to the int

I've used this syntax in the past...random(200)+100....and that'll still work in F5, at least to my knowledge. But with the Math object now, we would use as Jesse said....

progression and all

try it, see what happens, its the best way to learn...

trace((Math.random (200))+100);

MM say in the AS Dictionary that Math.random() is to return a decimal between 0 and 1. Random() is the old Flash 4 function, and it's not part of the Math class.. well not really, sinceit's not a method.
Method; returns a pseudo-random number between 0.0 and 1.0.
My point it that I don't think Math.random() is supposed to take an argument between the braces.

When I used this :

trace((Math.random (200))+100);

It turned (100. xxxxxxxxxxxxxxxx)
but when I added int, so it tured 100 always

so I used mine which in the first post here and it turned numbers with no dic. between 100 - 300

Thanks all
