/**
 * Calculates the ceiling of a number, i.e. rounds a number towards positive infinity. For arrays, the function will be applied index-wise to each element.
 * @param {(number|number[])} a a number or an array of numbers
 * @return {(number|number[])} The ceiling of `a`. Returns an array with the the ceilings of each element if `a` is an array.
 *
 * @example
 * ceil(1.2) // returns 2
 * ceil(-1.8) // returns -1
 * ceil([1.1, 2.2, 3.3]) // returns [2, 3, 4]
