org.apache.commons.math3.analysis.function.Rint
{@code rint} function. @since 3.0
org.apache.imperius.spl.parser.expressions.impl.Rint
org.apache.pig.piggybank.evaluation.math.RINT
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);
