Ceiling | >. 0 0 0 | Larger Of (Max)

`>.y` gives the ceiling of`y` ,`` that is, the smallest integer greater than or equal to `y` .`` Thus:

       >. 4.6 4 _4 _4.6
    5 4 _4 _4

The implied comparison with integers is tolerant, as discussed under Equal`` (`=`),`` and is controlled by`>.!.t` .`` See Floor`` (`<.`) `` and McDonnell [10] for complex arguments.

`x>.y` is the larger of`x` and`y` .`` For example:

       3>.4 _4
    4 3

       >./7 8 5 9 2
    9

       >./\7 8 5 9 2
    7 8 8 9 9

The comparison`x = >. x` determines whether`x` is an integer. Thus:

       Integer_test=: ] = >.      NB. See the definition of fork in Section II F.
       Integer_test 3 3.14 _5
    1 0 1

       f=: = >.                   NB. The same function may be defined by a hook.
       f 3 3.14 _5
    1 0 1

The ceiling`>. y` is equivalent to`-<.-y` .`` In other words, it is the dual of floor with respect to (that is, under) arithmetic negation:`>.` ↔`<.&.-` and`<.` ↔`>.&.-` .`` For example:

       (<.&.- ; >.) 4.6 4 _4 _4.6
    +---------+---------+
    |5 4 _4 _4|5 4 _4 _4|
    +---------+---------+
