Re: Decimals acting wierd : 5.3 * 3 = 15.899999999999999

Many thanks guys. I think I got some serious gaps in this regard. For now I'm going with NumberFormat and it fits me, I'll try BigDecimal if I need more !

Thanks !

Hey guys,

I had this problem hounting me since quite a while. I'm using double types in the equation above and I have this wierd precision result : 

5.3 * 3 = 15.899999999999999

This is not the first time at all and I already saw this with floats / without multiplication and so on. Before I spend few hours figuring out some test cases, can anyone give me any directions of where and what to search ? :)

Many thanks everyone !
