i got this trouble 

Vec3 works whit real numbers 
but block has this minusZero hurting mi calculations 

i need to calculate if an entity inside the block is close to the center on the block but block gets me BlockPos and entity gives me a vec3 
when i converty i t by self it works excep if the entity is not on the block -0 causing the calculate value to move towars +0   

 

anyway is there  alredy in minecraft a function to return a BlockPos passing a Vec3    habing in count this MinusZero thing ??

 

 

 

 

 

 

There's no such thing as -0. The corners of each block represent the BlockPos. The center of the block is offset by 0.5.
