## Summary

Function: float**llVecMag**( vector vec );

12 | Function ID |

0.0 | Forced Delay |

10.0 | Energy |

Returns a float that is the magnitude of the vector (the undirected nonnegative distance from **vec** to <0.0, 0.0, 0.0>).

• vector | vec |

## Caveats

## Examples

<lsl> default {

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

}

</lsl>## Notes

- Mathematically the formula for vector magnitude is
- llSqrt(vec.x * vec.x + vec.y * vec.y + vec.z * vec.z)
