mag()¶
Calculates the magnitude (or length) of a vector.
Examples¶
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | def setup():
x1 = 20
x2 = 80
y1 = 30
y2 = 70
py5.line(0, 0, x1, y1)
py5.println(py5.mag(x1, y1)) # Prints "36.05551"
py5.line(0, 0, x2, y1)
py5.println(py5.mag(x2, y1)) # Prints "85.44004"
py5.line(0, 0, x1, y2)
py5.println(py5.mag(x1, y2)) # Prints "72.8011"
py5.line(0, 0, x2, y2)
py5.println(py5.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 the coordinate (0, 0) to its (x, y) value. Therefore, mag() is a shortcut for writing dist(0, 0, x, y).
Syntax¶
mag(a: float, b: float) -> float
mag(a: float, b: float, c: float) -> float
Parameters¶
a: float - first value
b: float - second value
c: float - third value
