This would print a new number on each frame from 0 to frame 360:
t = timeToFrames(time);
if(t < 360) printf(t);
As Dan already mentioned, an expression can be thought of as a function that is evaluated on every frame. The last value given in the expression is the value that the property will take. Only the last value of your loop will be returned unless you break out of the loop when you've reached the value you're looking for.

what i was trying to do to a property is:
for ( x = 0; x < 360; x++ ) { printf( "%d\n", x ); }
but instead of the printf in C this would change the value of the property.

How do you animate a while loop in AE?
When I use it I just get the final return of the expression.
Also another question how do you invert the exponential curve from math.exp so things start slower and go fster at the end?
