⌈ Greater of

Two-argument form  See also one-argument form Ceiling

Finds the larger of two numbers. Each number in the right-hand argument is compared with the corresponding number in the left-hand argument. The result is the larger number from each comparison. (This operation is affected by ⎕CT, the comparison tolerance)
