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)".
