Cross-language random numbers

Oops, sorry! I’ve failed in spotting that class RandAnywhere was relying on p5::map() method:

At least you’ve found some implementation to replace it.

If you’re still interested, here’s the original p5::map() code (but yours is much better!):

processing/p5.js/blob/v1.4.0/src/math/calculation.js#L451-L462


      
          p5.prototype.map = function(n, start1, stop1, start2, stop2, withinBounds) {
            p5._validateParameters('map', arguments);
            const newval = (n - start1) / (stop1 - start1) * (stop2 - start2) + start2;
            if (!withinBounds) {
              return newval;
            }
            if (start2 < stop2) {
              return this.constrain(newval, start2, stop2);
            } else {
              return this.constrain(newval, stop2, start2);
            }
          };

Thanks for the map fix to make it more portable, @figle
