# ZCubes/Computations with Units and Range of Values

## Computations with Units and Range of Values

ZCubes computations are ‘units’ aware. This means you can pass units for computations such as velocity, acceleration, weight, speed etc, and ZCubes will do the computation with units and give the results in the appropriate units. You can also compute for a range of values by doing ‘arrayfy’ of a function.

Computations with Units and Range of Values

## Examples

E.g 1] If the parameters are entered along with the respective units, the final velocity 'V' is displayed with the appropriate unit.

//type 'arr' and pressing Shift+Space key gives an character '#', that defines an array

displays the resultant velocity 'V' as 50 m/s.

E.g 2] When changed the unit of time to 'hr', the resultant velocity changes accordingly.

//type 'arr' and pressing Shift+Space key gives an character '#', that defines an array

displays the resultant velocity 'V' as 176401 m/s.

E.g 3] The final velocity can be calculated for range of values of 'u' and 't' from 1 to 10 as shown below:

//type 'arr' and pressing Shift+Space key gives an character '#', that defines an array

The result is displayed as-

```u	 a	      t         V
```
