# Integer.ceil (from ruby core) --- ceil(ndigits = 0) -> integer --- Returns the smallest number greater than or equal to `self` with a precision of `ndigits` decimal digits. When the precision is negative, the returned value is an integer with at least `ndigits.abs` trailing zeros: 555.ceil(-1) # => 560 555.ceil(-2) # => 600 -555.ceil(-2) # => -500 555.ceil(-3) # => 1000 Returns `self` when `ndigits` is zero or positive. 555.ceil # => 555 555.ceil(50) # => 555 Related: Integer#floor.
