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);

          double actual = (new Double(output.strval())).doubleValue();
          assertEquals(actual, expected, delta);

   public void testCEIL() throws Exception{
       EvalFunc<DataAtom> CEIL = new CEIL();
          Tuple tup = new Tuple(1);
          tup.setField(0, 0.5);
          DataAtom output = new DataAtom();
          CEIL.exec(tup, output);
          double expected = Math.ceil(0.5);
          double actual = (new Double(output.strval())).doubleValue();
