org.apache.commons.math3.analysis.function.Ceil
{@code ceil} function. @since 3.0
org.apache.pig.piggybank.evaluation.math.CEIL
math.CEIL implements a binding to the Java function {@link java.lang.Math#ceil(double) Math.ceil(double)}. Given a single data atom it Returns the smallest (closest to negative infinity) double value that is greater than or equal to the argument and is equal to a mathematical integer.

Parameters:

value - DataAtom [double].

Return Value:

DataAtom [double]

Return Schema:

ceil_inputSchema

Example:

register math.jar; A = load 'mydata' using PigStorage() as ( float1 ); B = foreach A generate float1, math.ceil(float1);
