Dimension

```
public interface Dimension
```
Represents the dimension of a unit.
Concrete dimensions are obtained through the Unit.getDimension() method.

Two units u1 and u2 are compatible if and only if u1.getDimension().equals(u2.getDimension()).

- Method Detail
  - multiply
```
Dimension multiply(Dimension multiplicand)
```
    Returns the product of this dimension with the one specified.
    
    Parameters:
    
    multiplicand - the dimension multiplicand.
    
    Returns:
    
    this * multiplicand
  - divide
```
Dimension divide(Dimension divisor)
```
    Returns the quotient of this dimension with the one specified.
    
    Parameters:
    
    divisor - the dimension divisor.
    
    Returns:
    
    this / divisor
  - pow
```
Dimension pow(int n)
```
    Returns this dimension raised to an exponent. (thisⁿ)
    
    Parameters:
    
    n - power to raise this Dimension to.
    
    Returns:
    
    thisⁿ
  - root
```
Dimension root(int n)
```
    Returns the given root of this dimension.
    
    Parameters:
    
    n - the root's order.
    
    Returns:
    
    the result of taking the given root of this dimension.
    
    Throws:
    
    java.lang.ArithmeticException - if n == 0.
  - getBaseDimensions
```
java.util.Map<? extends Dimension,java.lang.Integer> getBaseDimensions()
```
    Returns the (fundamental) base dimensions and their exponent whose product is this dimension, or null if this dimension is a base dimension.
    
    Returns:
    
    the mapping between the fundamental dimensions and their exponent.
