Calculates the square root of a number.
A number's square root can be multiplied by itself to produce the original number. For example, sqrt(9) returns 3 because 3 × 3 = 9. sqrt() always returns a positive value. sqrt() doesn't work with negative arguments such as sqrt(-9).
sqrt() can also be used in shaders with p5.strands. The following example uses sqrt() to create a smooth ease-out curve on color and size.
Examples
Syntax
