random() Math Random Web & Application random_.jar for(int i=0; i<100; i++) { float r = random(50); stroke(r*5); line(50, i, 50+r, i); } random_2.jar for(int i=0; i<100; i++) { float r = random(-50, 50); stroke(abs(r*5)); line(50, i, 50+r, i); } Generates random numbers. Each time the random() function is called, it returns an unexpected value within the specified range. If one parameter is passed to the function it will return a float between zero and the value of the parameter. The function call random(5) returns values between 0 and 5. If two parameters are passed, it will return a float with a value between the the parameters. The function call random(-5, 10.2) returns values between -5 and 10.2. To convert a floating-point random number to an integer, use the int() function. random(value1); random(value1, value2); value1 int or float value2 int or float float noise() 1.0 Function Core
