Static p5_sys::global::randomGaussian

pub static randomGaussian: RandomGaussianInternalType

Returns a random number fitting a Gaussian, or normal, distribution. There is theoretically no minimum or maximum value that randomGaussian() might return. Rather, there is just a very low probability that values far from the mean will be returned; and a higher probability that numbers near the mean will be returned. Takes either 0, 1 or 2 arguments.
If no args, returns a mean of 0 and standard deviation of 1.
If one arg, that arg is the mean (standard deviation is 1).
If two args, first is mean, second is standard deviation.

Examples

 for (let y = 0; y < 100; y++) {
   let x = randomGaussian(50, 15);
   line(50, y, x, y);
 }

 let distribution = new Array(360);
function setup() {
   createCanvas(100, 100);
   for (let i = 0; i < distribution.length; i++) {
     distribution[i] = floor(randomGaussian(0, 15));
   }
 }
function draw() {
   background(204);
  translate(width / 2, width / 2);
  for (let i = 0; i < distribution.length; i++) {
     rotate(TWO_PI / distribution.length);
     stroke(0);
     let dist = abs(distribution[i]);
     line(0, 0, dist, 0);
   }
 }

Parameters

mean? the mean

sd? the standard deviation
