public class toRadians
extends DoubleBase

math.toRadians implements a binding to the Java function Math.toRadians(double). Given a single data atom it Converts an angle measured in degrees to an approximately equivalent angle measured in radians.

Parameters:
value - Double.
Return Value:
Double
Return Schema:
toRadians_inputSchema
Example:
register math.jar;
A = load 'mydata' using PigStorage() as ( float1 );
B = foreach A generate float1, math.toRadians(float1);
