org.apache.commons.math3.analysis.function.Tan
Tangent function. @since 3.0
org.apache.pig.piggybank.evaluation.math.TAN
math.TAN implements a binding to the Java function {@link java.lang.Math#tan(double) Math.tan(double)}. Given a single data atom it Returns the tangent of the argument.

Parameters:

value - DataAtom [double].

Return Value:

DataAtom [double]

Return Schema:

TAN_inputSchema

Example:

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