norm

NAME

norm() - the magnitude (Euclidean length) of a vector

SYNOPSIS

float norm(int * | float * vector)

DESCRIPTION

Returns the norm (magnitude) of 'vector', that is, the Euclidean length:
the square root of the sum of the squares of its elements. The result is
always a float.

Each element of 'vector' may independently be an int or a float; the two
may be mixed in the same array. An element of any other type raises a
runtime error ("norm: invalid argument 1.").

EXAMPLE

norm(({ 3, 4 }));       // 5.0
norm(({ 1.0, 2.0, 2.0 })); // 3.0
