Summary

Function: float llVecMag( vector vec );

Returns a float that is the magnitude of the vector (the undirected nonnegative distance from vec to <0.0, 0.0, 0.0>). It can be evaluated by doing llSqrt(vec.x*vec.x + vec.y*vec.y + vec.z*vec.z).

• vector vec

Examples

default {
    state_entry()
    {
        vector input = <1.0,2.0,3.0>;
        llSay(0,"The magnitude of "+(string)input+" is "+(string)llVecMag(input) + ".");
    }
}
