how to shorten coordinates ???

[Marobs]

hi,

I have in mine craftbuild a gps service.
Now i have the problem with the coordinates.
If i ask them trought the gps i get like x = 159.357 y = 65.349 z = 469.248.
now i want to shorten them so i only have left what is infront the dot.
like this x = 159 y = 65 z = 469.

how can i do this in lua code, i try to learn all i can from lua.
but some times need help. cant do it all alone.
its as they say, only together we can do it all.

thnx alot already for the help.

and btw im dutch so dont lock at type errors.

greets.
