exp() -- compute the exponential function of its single argument
This function computes e to the power of its argument, where e is the well known euler constant 2.71828182864. The exp-function is the inverse of the log-function.
window open 100,100 to 300,300, "Example", "Example"
for x=-100 to 100
draw dot x,100-100*exp(x/100)/euler, "Example"
window close "Example"
This program plots part of the exp-function, however the range is rather small, so that you may not recognize the function from this plot.
