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

Rob

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)

Thanks a million Dan. Perfect!
