Question

JavaScript => public var magnitude: float;
C# => public float magnitude;

Description 描述

Returns the length of this vector (Read Only).
返回向量长度(只读)。

The length of the vector is square root of (x*x+y*y+z*z+w*w).
向量长度是(x*x+y*y+z*z+w*w)的平方根。

If you only need to compare magnitudes of some vectors, you can compare squared magnitudes of them using sqrMagnitude (computing squared magnitudes is faster).
如果你需要比较一些向量的长度，你可以比较它们长度的平方，使用sqrMagnitude（计算平方很快）。
