Expression – random numbers with decimal point
Hello
Firstly can I say I am new to expressions. However I would like to know if there is a simple way of generating a random number with two further numbers after the decimal point.
e.g. 15.17
I have used the ‘Character Offset’ with a wiggle command – wiggle(1,5) but this only produces a two digit number with no decimal.
Does anyone know a work around?
Thanks

I’m not sure if this is exactly what you had in mind, but give this source text expression a try:
random(100).toFixed(2)

That’s fantastic thanks – just what I wanted.
One further question. Can the speed of the random numbers be controlled? (slowed down) For example, can the time between each change of digits be extended – so the each digit is on screen for longer.
Thanks

Something like this probably:
frames = 5; // frames to hold each random number
seed = Math.floor((time – inPoint)/framesToTime(frames));
seedRandom(seed,true);random(100).toFixed(2)
