Modifier and Type	Method	Description
`boolean`	`compare(boolean in1, boolean in2)`
`boolean`	`compare(double in1, double in2)`
`boolean`	`compare(long in1, long in2)`
`boolean`	`compare(String in1, String in2)`
`double`	`execute(double in1, double in2)`	execute() method that returns double is required since current map-reduce runtime can only produce matrices of doubles.

public static LessThan getLessThanFnObject()
```
  - execute
```
public double execute(double in1,
                      double in2)
```
    execute() method that returns double is required since current map-reduce runtime can only produce matrices of doubles. This method is used on MR side to perform comparisons on matrices like A<B and A<2.5
