sqrt() Math Calculation Web & Application sqrt_.gif noStroke(); float a = sqrt(6561); // Sets a to 81 float b = sqrt(625); // Sets b to 25 float c = sqrt(1); // Sets c to 1 rect(0, 25, a, 10); rect(0, 45, b, 10); rect(0, 65, c, 10); Calculates the square root of a number. The square root of a number is always positive, even though there may be a valid negative root. The square root s of number a is such that s*s = a. It is the opposite of squaring. sqrt(value) value int or float: non-negative number float pow() sq() 1.0 Function PDE
