Some calculations need to use a random number generator. The examples below will help you with this.
Random number from -100 to +100
Use when you need to randomly add or subtract a number. If you multiply any number by this expression, it will randomly determine its sign (Plus or Minus), which will allow you, for example, to randomly add or subtract a value in a variable (or a bonus, for example).
To determine (Plus / Minus) sign, let's use a rands() function from the Expressions Manual. The function randi() will generate a random number between 1 and 100, and multiplying it by the function value of rands() will make the result negative or positive. Thus, a random number from -100 to -1 and from +1 to +100 (not zero) will be returned.
The final expression will look like this:
{randi(1, 100) * rands()}
