# BigDecimal.ceil (from ruby core) --- ceil(n) --- Return the smallest integer greater than or equal to the value, as a BigDecimal. BigDecimal('3.14159').ceil #=> 4 BigDecimal('-9.1').ceil #=> -9 If n is specified and positive, the fractional part of the result has no more than that many digits. If n is specified and negative, at least that many digits to the left of the decimal point will be 0 in the result. BigDecimal('3.14159').ceil(3) #=> 3.142 BigDecimal('13345.234').ceil(-2) #=> 13400.0
