ceil(p1 = v1) public

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
