# Normalize proc (vector)

Added in BYOND 516.

### Format
> `V.Normalize()`

### Returns
> The same vector, after normalizing it to a unit vector.

Modifies the vector to make it a unit vector. This is the same as setting its `size` var to 1.

A degenerate vector such as 0,0,0 cannot be normalized; it will be unchanged by this call.
