well, i CAN't tell you how to do it using LN cause it's too difficult to even explain why I can't do it.  but I CAN tell you how to make your code work. Like this
y=exp(-100*x)/100000;
then whenever you're using the number in an equation, simply multiply it by 100000


This should work under almost every circumstance.
You do realize that you're winding up with a HUGE number
