Name
angle - return the angle between two vectors
Synopsis
float angle( vector v1, vector v2 );
Description
"vector" is not actually a type in LPC. It is used here to represent an array of ints and/or floats.
angle( v1, v2 ) will return the angle between the vectors `v1' and `v2'.
`v1' and `v2' must be of the same size, otherwise a runtime is produced.
