math.RINT implements a binding to the Java function {@link java.lang.Math#rint(double) Math.rint(double)}. Given a single data atom it Returns the double value that is closest in value to the argument and is equal to a mathematical integer.

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