Oneargument form See also twoargument form Greater of The number or numbers in the righthand argument are rounded up to the next whole number. ⌈ 45.9 46 ⌈ ¯3.8 (Note effect of rounding up on a ¯3 negative number) ⌈1.2 ¯0.3 99.1 2.8 (Each number in a vector is rounded up) 2 0 100 3 ⌈¯0.5+1.2 ¯0.3 9.1 2.8 (0.5 is subtracted from each number 1 0 9 3 before ⌈ is applied, producing 'true' rounding) TABLE 62.8 3.0 ¯2.9 9.1 7.3 0.01 ⌈ TABLE (Each number in TABLE is rounded up) 63 3 ¯2 10 8 1 ⌈(1.7 11.99 ¯2.3) (2 2⍴¯1.1 17.3 ¯0.1 103.4) 2 12 ¯2 ¯1 18 (Each element is rounded up) 0 104 Comparison toleranceWhen acting on a number which is very close to but slightly bigger than an integer, Ceiling may round down to that integer rather than round up. This will happen if the argument is within comparison tolerance of the integer, and is therefore considered in APL to be equal to it. Effect on internal representationSee the description of
