Seems you forgot the indices in the prime version of your attempt.

Why don't you just use the absolute value

vcrossa_length:=|vcrossa|

What you did in Prime was to take the square root of (three times the square of the length of your vector).

In other words you calculated the length of the vector times the square root of 3.
