Examples of Acos

org.apache.commons.math3.analysis.function.Acos
Arc-cosine function. @since 3.0
org.apache.pig.piggybank.evaluation.math.ACOS
math.ACOS implements a binding to the Java function {@link java.lang.Math#acos(double) Math.acos(double)} for computing thearc cosine of value of the argument. The returned value will be a double which is the arc cosine of the value of input.

Parameters:

value - DataAtom [double].

Return Value:

DataAtom [double] arc cosine of the value of input

Return Schema:

acos_inputSchema

Example:

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