ceil, floor...

Hi,
I thought Math.ceil and floor returns double NOT int.
but I came across couple of questions saying that it returns int.
I ran the code myself. it returns double..
Can someone confirm, please?
Thanks

Hi Sean,
Sun's API documentation says that
ceil(double a) Returns the smallest (closest to negative infinity) double value that is not less than the argument and is equal to a mathematical integer.

floor(double a) Returns the largest (closest to positive infinity) double value that is not greater than the argument and is equal to a mathematical integer.

Hence it should return double...
HTH....

Hi Sean . The ceil and floor methods of Math class return INTEGRAL values as double values and not primitive type int.Thus if u say floor(13.2) it will return 13.0 , which is an integral value(13) converted to a double value , i.e 13.0.
I hope I have been clear enough.

So it won't return 13 . right? 13.0 instead...
