sq() Math Calculation Web & Application sq_.gif noStroke(); float a = sq(1); // Sets a to 1 float b = sq(-5); // Sets b to 25 float c = sq(9); // Sets c to 81 rect(0, 25, a, 10); rect(0, 45, b, 10); rect(0, 65, c, 10); Squares a number (multiplies a number by itself). The result is always a positive number, as multiplying two negative numbers always yields a positive result. For example, -1 * -1 = 1. sq(value) value int or float float sqrt() 1.0 Function PDE
