math.SQRT implements a binding to the Java function {@link java.lang.Math#sqrt(double) Math.sqrt(double)}. Given a single data atom it Returns the square root of the argument.

Parameters:

value - DataAtom [double].

Return Value:

DataAtom [double]

Return Schema:

SQRT_inputSchema

Example:

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