adding a % of some variable

Rafe · June 2015

I'm now trying to get harlowe to add some % of the number on one of the variables. Say, there is a stock market where you can invest, and they will help you save or lose you money.

Something like this:

(set: $stock1savings to $stock1price + (random: %-10,%25))

As explained by this link, to calculate a percentage of a value you first multiple the value by the percent you want and then you divide that by 100.

eg. You want to calculate twenty percent of three hundred:

20% of 300   =>   (20 * 300) / 100   =>   6000 / 100   =>   60

If you wanted to add that percentage to the original value, it would look something like the following:

300 + ((20 * 300) / 100)   =>  300 + 60   =>  360

Using your example:

(set: $stock1savings to $stock1price + (((random: -10, 25) * $stock1price) / 100))

I figured out there could be a way to make it simpler, since when I add a % sign, it tells me I need something to its right.

Howdy, Stranger!
