Sine function. @since 3.0
org.apache.pig.piggybank.evaluation.math.SIN
math.SIN implements a binding to the Java function {@link java.lang.Math#sin(double) Math.sin(double)}. Given a single data atom it Returns the sine of the argument.

Parameters:

value - DataAtom [double].

Return Value:

DataAtom [double]

Return Schema:

SIN_inputSchema

Example:

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