# mag()

# 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 the coordinate 0,0 to its x,y value. Therefore, mag() is a shortcut for writing dist(0, 0, x, y).

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"
