org.apache.pig.piggybank.evaluation.math.IEEEremainder

math.IEEEremainder implements a binding to the Java function {@link java.lang.Math#IEEEremainder(double,double) Math.IEEEremainder(double,double)}. Given a tuple with two data atom it Returns the remainder operation on two arguments as prescribed by the IEEE 754 standard.

Parameters:: value - Tuple containing two DataAtom [double].
Return Value:: DataAtom [double]
Return Schema:: IEEEremainder_inputSchema
Example:: register math.jar; A = load 'mydata' using PigStorage() as ( float1 ); B = foreach A generate float1, math.IEEEremainder(float1);

          double actual = (new Double(output.strval())).doubleValue();
          assertEquals(actual, expected, delta);
      }
   
   public void testIEEEremainder() throws Exception {
          EvalFunc<DataAtom> IEEEremainder = new IEEEremainder();
          Tuple tup = new Tuple(2);
          tup.setField(0, -0.5);
          tup.setField(1,0.6);
          DataAtom output = new DataAtom();

          double expected = Math.IEEEremainder(-0.5,0.6);
