Name  mag() 


Examples  float x1 = 20; float x2 = 80; float y1 = 30; float y2 = 70; line(0, 0, x1, y1); println(mag(x1, y1)); // Prints 36.05551 line(0, 0, x2, y1); println(mag(x2, y1)); // Prints 85.44004 line(0, 0, x1, y2); println(mag(x1, y2)); // Prints 72.8011 line(0, 0, x2, y2); println(mag(x2, y2)); // Prints 106.30146 

Description  Calculates the magnitude (or length) of a vector. A vector is a direction in space commonly used in computer graphics and linear algebra. Because it has no "start" position, the magnitude of a vector can be thought of as the distance from coordinate (0,0) to its (x,y) value. Therefore, mag() is a shortcut for writing "dist(0, 0, x, y)". 

Syntax
