To get the length of a string, or number of items in an array, use len.
float length(float f)
Simply returns the given number.
float length(vector2 v)
float length(vector v)
float length(vector4 v)
Returns the distance of the vector or vector4 from the origin.
If you want the squared length, using length2 is faster than squaring the result of this function.
Examples ¶
length({1.0, 0, 0}) == 1.0; length({1.0, 1.0, 0}) == 1.41421;
