Question: Help about "Determinant"

1. I have a Matrix V as following, and I found that Determinant(V,method=float) can not work. I use Maple12. Please help me , thanks.

2. also, in some calculations, I found Determinant(V,method=float) and Determinant(V,method=minor) gave different result. Anyone can tell me why?And which method is right?

V=[[0.2412702414,0.4868267037+4.770943828 10^(-17) I,-0.3582351644-3.597026404 10^(-14) I,0.8897131421,0.3035225208,0.2809455226],[0.5973344699,-1.205280722,1.019534434+1.083003890 10^(-16) I,0.3180937441 I,1.086504807,0.8732682510],[0.2412702414,0.4868267037+4.770943828 10^(-17) I,-1.684358576,-0.05461705659,0.3035225208,1.541076357],[513.8528507 I,-1036.834415 I,902.2703878 I,1198.784852,265.8824916 I,22.70515338 I],[5282.465108 I,10658.77442 I,-9122.190610 I,240.7412056 I,-1264.792778 I,-1175.059018 I],[3753.443600 I,-7573.567988 I,25898.97068 I,-9.080952395,-972.5394523 I,-4271.851836 I]]
