Expression number generator

Apr 15, 2012 4:14 PM

New to expressions

What I have so far I have this is the text source

Math.round(random(100).toFixed(2))

Which gives me randomly generated numbers without a decimal

What I need

Fixed characters right after those numbers

The numbers to stop on a set value at a set moment

Also how would I do a countdown (instead of random) and adjust the speed of it.

You could just tie your math round function to a slider and a multiplier. It should be very easy to figure out. Then just animate the slider.

V = slider value; (pickwhip to the expression slider)
Math.round(V)

You sound confusing. Does you countdown need to have any randomness? If not, Dan's solution would be as simple as it gets. If you need randomness, you could still use it and simply add your randomness, but you'd need a second slider for the randomness intensity, so you can stop it when you need to...

Ok the slider works, now how do I add additional fixed characters to the end of my numbers? Like a % sign or anything

Basics of JavaScript - string concatenation. Anything additioanl goes in quotation marks and is added:

Math.round(V)+"%"
